However, it’s not a fully organic product. It offers a good compromise for those seeking to reduce their environmental impact without sacrificing sleep quality or breaking the bank on a fully organic mattress.In the quest for the perfect night’s sleep, mattress technology has come a long way from the lumpy, spring-filled rectangles of yesteryear.The Amerisleep AS2 is one such mattress that promises to revolutionize your sleep experience through cutting-edge materials and thoughtful design. But in a market flooded with options, does the AS2 truly stand out, or is it just another drop in the sea of sleep solutions?I approached the AS2 with a mix of curiosity and healthy skepticism. After all, claims of cooler sleep, perfect support, and eco-friendly materials are common in the industry.What I discovered was a mattress that’s full of surprises. From its impressive cooling capabilities that had me rethinking my stance on memory foam, to its remarkable ability to isolate motion (sorry, midnight snackers, your secret trips to the fridge are no longer safe), the AS2 proved to be more than just another mattress in a box.But it wasn’t all sweet dreams and cool breezes. As with any product, there were quirks and considerations that might make some sleepers think twice. After all, the perfect mattress for one person might be a nightmare for another.Let’s peel back the layers (literally and figuratively) of this intriguing sleep solution and see if it lives up to the promise of transforming your nights and energizing your days.

Claim Deal Inside the Amerisleep AS2: Materials and ConstructionUpon opening the box, I found the Amerisleep AS2 neatly rolled and vacuum-sealed in plastic. The unboxing process was straightforward—I simply removed the rolled mattress, placed it on my bed frame, and carefully cut away the plastic wrapping. As soon as I made the first cut, the mattress began to expand with a soft whooshing sound.One of the first things I noticed was the lack of strong off-gassing odors that often accompany newly unboxed foam mattresses. The AS2 had only a faint, neutral smell that dissipated quickly. This was a pleasant surprise and a testament to Amerisleep’s use of plant-based materials in their Bio-Pur® foam.I allowed the mattress to expand for about 24 hours before sleeping on it, as recommended by Amerisleep. During this time, I observed the mattress taking shape, reaching its full 12-inch height and filling out to its queen size dimensions.The moment I first laid my hand on the fully expanded AS2, I was struck by the cool-to-the-touch sensation of the cover. It piqued my interest in how the mattress would perform in terms of temperature regulation during a full night’s sleep.As I prepared to dive deep into testing the AS2, I was eager to explore how each layer would contribute to the overall sleep experience. From the innovative cover to the zoned support system, each component promised a unique contribution to the mattress’s performance.Cover FabricThe moment I lay down on the AS2, I notice the cool-to-the-touch sensation of the Refresh Cover. This isn’t just a momentary feeling, as throughout the night, I find that the cover consistently helps regulate my body temperature.As someone who tends to sleep hot, I appreciate how this cover seems to actively work to keep me cool. The mineral-based technology that converts body heat into far infrared energy isn’t just marketing speak. I genuinely feel a difference in sleep quality compared to mattresses with standard covers.Comfort FoamDirectly beneath the cover, the Bio-Pur® foam layer offers an intriguing balance of comfort and responsiveness. When I first lie down, I feel the foam contouring to my body, much like traditional memory foam. However, the difference becomes apparent when I change positions.Unlike some memory foam mattresses that leave me feeling “stuck,” the Bio-Pur® foam responds quickly to my movements. This responsiveness, combined with its pressure-relieving properties, means I wake up with fewer aches and pains, particularly in my lower back and shoulders.Transition LayerThe HIVE® layer is where I really feel the AS2 differentiates itself in terms of support. As a combination sleeper who alternates between back and side sleeping, I notice how this layer provides varied support to different parts of my body.When I’m on my back, I feel firmer support under my lower back, which helps maintain proper spinal alignment. When I shift to my side, I appreciate the softer support around my shoulders and hips, which allows these areas to sink in just enough to keep my spine straight.This zoned support system isn’t just comfortable—it’s functional. After testing the AS2 for an extended period, I’ve noticed a significant reduction in the morning stiffness I often experience with less supportive mattresses.Support LayerWhile I can’t directly feel the Bio-Core® layer, its presence is evident in the overall feel of the mattress. The AS2 maintains its shape and support, even after months of use.I’ve tested mattresses that start to develop soft spots or sag after prolonged use, but the AS2 shows every sign of maintaining its consistent feel. This is particularly noticeable when I sit on the edge of the bed—the support is uniform right to the edges, which isn’t always the case with memory foam mattresses.Testing Sleep PositionsOur bodies interact differently with a sleep surface depending on whether we’re on our side, back, or stomach. So when it comes to mattress testing, understanding how a bed performs across different sleep positions is crucial.The Amerisleep AS2, with its medium-firm feel and innovative layered construction, presents an interesting case study in sleep position versatility.Side SleepingAs a combination sleeper who often favors my side, I was particularly interested in how the AS2 would perform in this position. I’m pleased to report that despite its medium-firm classification, the AS2 wasn’t too firm as a mattress for side sleeping.This was a pleasant surprise, as I know that overly firm mattresses can lead to sore hips and shoulders in the morning.The Bio-Pur® foam did an excellent job of contouring to my hip and shoulder, providing pressure relief in these key areas. The HIVE® technology again proved its worth, offering softer support in the hip area while maintaining firmness elsewhere to keep my spine aligned.I would still recommend the Amerisleep AS3 or AS5 options if you’re primarily a side sleeper. But for those who might occasionally roll into the position as they sleep, the AS2 is a fine option!Back SleepingWhen I first lay down on my back, I immediately noticed how the mattress contoured to my body. The medium-firm feel provided excellent support for my lower back, which is crucial in back sleeping mattresses for proper spinal alignment.The HIVE® technology was particularly noticeable in this position. I could feel increased support in my lumbar region, while my shoulders had just enough give to remain comfortable. This targeted support system really shines for back sleepers.And the Bio-Pur® foam responded quickly to my movements, preventing that “stuck” feeling often associated with memory foam.Stomach SleepingRolling onto my stomach, I found the AS2 to be particularly well-suited for this sleep position. The firmness level was just right to keep my hips from sinking too deeply, which is crucial in mattresses for stomach sleepers to avoid lower back strain.The cooling properties of the mattress were especially noticeable in this position, as stomach sleeping tends to trap body heat against the mattress. The Refresh Cover and open-cell structure of the Bio-Pur® foam kept me feeling cool and comfortable throughout the night.Combination SleepingThose prone to rolling into new positions as they sleep need a mattress that can keep up. Now usually, I start on my side when I fall asleep, though I may wake up in a different position.When transitioning to my back or stomach on the AS2 to mimic restless sleep, I appreciated the responsiveness of the Bio-Pur® foam. It allowed for easy movement without feeling stuck, which is crucial in mattresses for combination sleepers.The HIVE® transition layer especially offered noticeable support, particularly in my lower back when on my back, and kept my hips from sinking too deeply when on my stomach.How Responsive Is the Mattress?Mattress responsiveness refers to how quickly a mattress recovers its shape after pressure is applied and removed. In simpler terms, it’s how fast the mattress “bounces back” when you move or change positions during sleep.A responsive mattress makes it easier to change sleeping positions during the night, which is crucial for combination sleepers. And when you first lie down, a responsive mattress will conform to your body shape faster, potentially reducing the time it takes to get comfortable.Meanwhile, less responsive mattresses, especially traditional memory foam, can create a sinking feeling that some sleepers find uncomfortable.Testing the mattress was a simple enough matter, as I essentially flopped down onto the bed and observed how fast the mattress reacted to my actions. Overall, I conducted four distinct tests:Press Test: I pressed my hand firmly into different areas of the mattress for 30 seconds, then quickly removed it. I timed how long it took for the mattress to fully regain its shape. The AS2 consistently recovered in under 3 seconds, which is excellent for a foam mattress.Roll-Over Test: I lay on the mattress and timed how long it took me to change positions from my back to my side, and then to my stomach. The AS2 allowed for smooth and easy transitions, with minimal effort required to move.Bounce Test: I dropped a 10-pound ball weight from a height of 6 inches above the mattress surface and measured the bounce. The AS2 showed a moderate bounce, allowing the weight to rise about 2 inches on the rebound.Body Impression Test: After lying in one position for an hour, I moved and observed how quickly the mattress regained its original shape. The AS2 bounced back almost immediately, leaving no visible body impression after just a few seconds.While the AS2 scores exceptionally high in responsiveness, there’s always room for improvement. Some sleepers might prefer the sink-in feel of less responsive memory foam. Additionally, while it’s responsive for a foam mattress, it still doesn’t match the springiness of a coil mattress. Mattress Responsiveness Score 9 out of 10How Well Does the Mattress Isolate Motion?Motion isolation refers to a mattress’s ability to absorb and minimize the transfer of movement from one part of the bed to another. In other words, it’s how well the mattress prevents you from feeling your partner’s movements on the other side of the bed.If you or your partner is easily awakened by movement, excellent motion isolation can significantly improve sleep quality. And couples with different sleep patterns or daily schedules can coexist more harmoniously on such a mattress.I’ve shared mattresses for two with restless partners and energetic pets, I’ve become acutely aware of how crucial good motion isolation is for a peaceful night’s sleep. On this front, the AS2 truly excels, earning a perfect 10 out of 10 in my book.Along with the real world experience that comes from sleeping on the bed with another person, I conducted a few tests to simulate the tossing-and-turning experience:Partner Simulation Test: With a sleep partner, we took turns moving, changing positions, and getting in and out of bed while the other person lay still with eyes closed. Neither of us could detect the other’s movements, even when actively trying to feel them.Drop Test: I dropped a weighted object from a height of about 6 inches onto one side of the mattress and observed the movement on the other side. The AS2 absorbed the impact impressively, with minimal to no noticeable motion transfer.Pressure Point Test: I applied firm pressure at various points on the mattress while my partner lay on the other side. The localized compression was impressive, with minimal transfer of movement to other areas of the bed.The Night Movement Log: I keep a log of how often I’m awakened by my partner’s movements during the night. With the AS2, these instances are remarkably rare to non-existent, as I could not be sure what stirred me from my sleep the few times I woke up early.From the very first night on the AS2, I noticed a significant difference in how still the bed remained despite movement. My partner, who tends to be a restless sleeper, was amazed at how little his tossing and turning seemed to affect my side of the bed.What impressed me most about the AS2’s motion isolation wasn’t just how it handled big movements, but the way it dampened smaller, more subtle motions. Things like my partner shifting position or reaching for a glass of water on the nightstand – movements that used to create small but noticeable disturbances – were now almost imperceptible.This level of isolation isn’t just about preventing wake-ups; it’s about maintaining deeper, more restorative sleep throughout the night. I found myself waking up feeling more refreshed, likely because the AS2 was allowing me to stay in deeper sleep stages without micro-disturbances.For couples, this means one partner can move freely without fear of disturbing the other. Light sleepers will appreciate the AS2’s ability to dampen even subtle movements, potentially leading to fewer sleep interruptions and more restful nights. Mattress Motion Isolation Score 10 out of 10How Does the Edge Support Hold Up?Edge support refers to how well a mattress holds up around its perimeter when weight is applied. Strong edge support maintains the mattress’s structure and prevents sagging or collapsing when you sit or lie near the edge. No need to fear feeling like you’re going to roll off!The stable edges also make it easy to get in and out of bed, which is particularly beneficial for those with mobility issues or injuries.Strong edge support also tends to go hand in hand with good mattress durability, indicating that the materials will maintain their shape and support over time.I’ve bounced and bobbed my way along many a mattress’s edge, seeing how it serves as an impromptu shelf for my body. And I can confidently say that the Amerisleep AS2 excels in edge support, earning a perfect 10 out of 10 in my rigorous tests. This exceptional score places it at the top of its class, even outperforming lesser hybrid and innerspring mattresses.Sit Test: I sat on the edge of the mattress in various positions – upright with feet on the floor, and sideways as if getting into bed. The AS2 showed minimal compression, providing stable support in all positions.Lie Test: I lay on the very edge of the mattress in different sleep positions (side, back, stomach). Remarkably, I felt just as supported as I did in the center of the mattress, with no sensation of rolling off.Stand Test: I stood on the edge of the mattress, simulating the stress of getting in and out of bed over time. The AS2 maintained its shape exceptionally well, with minimal sagging.Weight Test: I placed a 20-pound weight on the edge of the mattress for 8 hours to simulate prolonged stress. Upon removal, the mattress immediately regained its shape with no visible indentation.I performed these tests on various parts of the mattress edge and compared the results to the center of the mattress. The edge support was consistently excellent across all areas, which I thank the bed’s high-density foams for. They are designed to work together to distribute weight evenly, preventing excessive compression at the edges.The AS2’s firmer feel also contributes to its robust edge support. Overall, I’ve found that firmer mattresses generally perform better in this area than softer ones.The Amerisleep AS2’s edge support score of 10/10 is truly exceptional, especially for an all-foam mattress. You can comfortably sleep or sit right up to the edge without feeling like you’re going to roll off. Partners can also spread out and use the entire mattress surface without feeling confined to the center. Mattress Edge Support Score 10 out of 10How Long Should the Mattress Last?As a mattress tester who’s seen countless beds come and go, I’m often asked about the expected lifespan of a mattress. But I’ve got to be upfront: predicting exact mattress longevity is more art than science.However, based on its construction, materials, and my experience with similar mattresses, I can offer an educated guess about a bed’s durability. While the average lifespan of a mattress is typically around 7-10 years, I wouldn’t be surprised if the AS2 outlasts this average, potentially serving sleepers well for 8-12 years or even longer with proper care.Now, I want to emphasize that this is indeed a guesstimate. How long a mattress lasts can vary widely based on factors like usage, care, body weight, and even climate (the wetter, the worst it is for the materials).But let’s dive into why I’m optimistic about the AS2’s durability:High-Density Foams: The AS2 uses high-quality, dense foams, particularly in its Bio-Core® base layer. Higher density generally correlates with better durability in foam mattresses. This robust base should help the mattress maintain its structure and support over time.Bio-Pur® Foam: Amerisleep’s proprietary Bio-Pur® foam is designed to be more resilient than traditional memory foam. Its open-cell structure not only aids in cooling but also helps the foam bounce back more quickly, potentially reducing the likelihood of permanent body impressions.HIVE® Technology: The targeted support provided by the HIVE® layer may help distribute weight more evenly across the mattress, potentially slowing down wear in typically high-stress areas like the hips and shoulders.Temperature Regulation: The cooling features of the AS2, including the Refresh Cover and breathable Bio-Pur® foam, can help mitigate heat buildup. This is significant because excessive heat can accelerate foam degradation over time.Warranty: Amerisleep offers a 20-year warranty on the AS2. While this doesn’t guarantee the mattress will last that long, it does suggest the company’s confidence in its product’s durability.Even with these positive factors, though, it’s important to understand how the AS2 might age. Namely, that the top comfort layer may soften slightly over time, which is normal for any foam mattress. Yes, even a firmer one like the AS2You might also notice slight body impressions forming, especially in areas where you consistently sleep. However, the responsive nature of the Bio-Pur® foam should help minimize this.The edge support, while initially strong for an all-foam mattress, may also diminish somewhat over years of use. The best approach is to pay attention to how your mattress performs over time and to replace the mattress when it no longer provides the comfort and support you need for a good night’s sleep.Still, in my professional opinion, if you’re investing in an AS2, you’re likely making a choice that will serve you well for many years to come. Just remember to treat it well, and it should return the favor with years of comfortable sleep as a mattress that won’t sag.Does the Mattress Sleep Cool?Temperature regulation is crucial for quality sleep. Overheating during the night can lead to restlessness, frequent awakenings, and less time spent in restorative deep sleep stages.A bed that stays cool provides consistent comfort throughout the night, regardless of room temperature fluctuations. A cooling mattress can also help you fall asleep more quickly by facilitating the natural drop in body temperature that occurs as you drift off.After experiencing one too many sweaty and restless nights on subpar sleep surfaces (and to be clear, just one bad night is one too many), I’ve internalized just how important it is for a mattress to keep me cool at night. When testing a mattress for its cooling ability, I can fill pages with what’s working and what’s not.Having tested other Amerisleep mattresses, I was pleased but not surprised to have the AS2 excel in cooling performance, earning a perfect 10 out of 10 in my evaluation As a hands-on tester, I use several simple yet effective methods to evaluate a mattress’s cooling capabilities:The Hand Test: I place my hand on the mattress surface for 30 seconds, then quickly remove it. The AS2 consistently feels cool to the touch, and the spot where my hand was returns to its original temperature almost immediately.The Lying Test: I lie on the mattress for 10 minutes, then move to a different spot. On the AS2, I notice very little heat retention in the area I just vacated, indicating excellent heat dissipation.The Night Sweat Test: As someone prone to night sweats, I pay close attention to how often I wake up feeling uncomfortably warm. With the AS2, these instances are virtually non-existent.The Partner Test: I enlist a sleep partner to share the bed, as two bodies generate more heat. Even with two people, the AS2 maintains a comfortable temperature throughout the night.The Blanket Test: I sleep with a heavy blanket to simulate warmer conditions. The AS2 still manages to keep me cool, showing its effectiveness even under challenging circumstances.The Morning Assessment: Upon waking, I immediately note if I feel overheated or if the mattress feels warm. With the AS2, I consistently wake up feeling comfortably cool.In real-world use, the AS2’s cooling capabilities truly shine. Even on warm nights or after intense physical activity before bed, the AS2 maintained a consistently cool and comfortable sleep surface.Whether you’re a naturally hot sleeper, live in a warm climate, or simply value the benefits of a cool night’s sleep, the AS2’s superior cooling properties are likely to significantly enhance your sleep quality. Combined with the mattress’s other qualities like pressure relief and support, makes the AS2 a top contender for those seeking a premium sleep experience.In a market where overheating is a common complaint with foam mattresses, the AS2’s perfect cooling score helps it stand out as a truly innovative and high-performance option for discerning sleepers. Mattress Cooling Score 10 out of 10Measuring the Environmental ImpactIn today’s world, the environmental impact of our purchases is becoming increasingly important. As a mattress tester who’s seen the industry evolve, I’ve noticed a growing trend towards eco-friendly sleep solutions.The Amerisleep AS2 is part of this movement, offering a balance between comfort and environmental consciousness.Eco-Friendly MaterialsThe standout feature of the AS2 is its Bio-Pur® foam. Unlike traditional memory foam, which is entirely petroleum-based, Bio-Pur® incorporates plant-based oils in its production. This partial replacement of petrochemicals with renewable resources is a step in the right direction for reducing the mattress’s carbon footprint.All foams used in the AS2 are CertiPUR-US® certified. This certification ensures that the foams are made without ozone depleters, certain flame retardants, mercury, lead, and other heavy metals. It also guarantees low VOC (Volatile Organic Compound) emissions for indoor air quality.During my sleep tests, I experienced minimal off-gassing, which is a common concern with foam mattresses.Manufacturing PracticesAmerisleep prides itself on its zero-emissions manufacturing process. This means that during the production of the AS2, no harmful chemicals are released into the atmosphere. It’s a significant step towards reducing the environmental impact of mattress production.This clean manufacturing process not only benefits the environment but also potentially the end-user. In my experience, eco-friendly mattresses produced in this way tend to have less chemical odor when first unboxed.Packaging and ShippingThe AS2 employs a compression packing method that significantly reduces its size for shipping. This efficient packaging means that more mattresses in boxes can fit on a single delivery truck, reducing the overall carbon emissions associated with transportation.When I received my AS2 for testing, I was impressed by how compact the package was. Once unboxed, the mattress expanded quickly to its full size without any loss in quality or comfort.Durability and LongevityOne often overlooked aspect of environmental impact is a product’s lifespan. A durable mattress that lasts longer means fewer mattresses in landfills over time. The AS2, with its high-density foam layers and quality construction, seems built to last.During my durability tests, the AS2 showed good resilience to regular use. The Bio-Pur® foam, in particular, seemed to maintain its shape and support better than some traditional memory foams I’ve tested. While only time will tell its true longevity, the signs point to a mattress that should serve sleepers well for many years.Balancing Eco-Friendliness with Other ConcernsWhile the AS2’s green features are impressive, it’s crucial that a mattress performs its primary function well. In my sleep tests, I found that the AS2 doesn’t compromise on comfort or support in its quest for eco-friendliness.Its medium-firm feel provided excellent support for back and stomach sleepers, while the Bio-Pur® foam offered enough contouring for most side sleepers. The improved breathability of the plant-based foam also contributed to a cooler sleep experience compared to traditional memory foam.Despite its eco-friendly features, it’s worth remembering the mattress still contains a significant portion of petroleum-based materials. Additionally, the adhesives used in the mattress construction may not be as environmentally friendly as the foams themselves.But still, I argue that every step towards more sustainable products counts. The AS2 might not be perfect, but it’s part of a larger movement pushing the mattress industry towards greener practices.While organic mattresses are wonderful, the simple fact is they are not accessible to everyone, often because of their higher prices. So the AS2 offers a solid compromise for those seeking to reduce their environmental impact without sacrificing sleep quality or overspending on a new mattress.Potential DrawbacksWhile the Amerisleep AS2 has many positive features, it’s important to step outside a cozy, rosy view to consider its design’s drawbacks. As someone who’s thoroughly tested this mattress and has devoured dozens of other reviews on it, here are some possible limitations I’ve observedFirm Feel Not for EveryoneIf you prefer the plush, enveloping feel of a soft mattress, the AS2 might feel too firm. It’s still a high-quality mattress that will suit many, especially back and stomach sleepers, but it’s not perfect for everyone.Individuals under 130 pounds might also not sink in enough to fully engage the comfort layers, potentially feeling like they’re sleeping “on” rather than “in” the mattress. Conversely, heavier sleepers over 230 pounds might sink too deeply into the foam layers, compromising spinal alignment.Price PointWhile the AS2 offers good value for its quality, its price point might be a drawback for some. Those looking for a more affordable memory foam bed might find the AS2’s price tag a bit steep.Some might question whether the additional features justify the higher cost compared to simpler foam mattresses like the Zoma Start or the Vaya Mattress.Edge Support ConcernsAlthough the edge support is good for an all-foam mattress, it’s not reinforced like a hybrid’s typically is. Potentially, it could wear out before the rest of the bed does, and this can be especially concerning for couples sharing a smaller mattress or those with mobility issues.Limited BounceWhile the Bio-Pur® foam is more responsive than traditional memory foam, it still doesn’t provide the level of bounce you’d get from an innerspring or hybrid mattress. Those who change positions frequently during the night might find it requires more effort to move around.Potential Off-GassingLike many foam mattresses, the AS2 may emit a temporary odor when first unboxed, as some other reviewers noted. While this is typically harmless and dissipates within a few days, it could be a concern for individuals sensitive to smell.If you’re hoping to sleep on your new mattress the first night, the off-gassing might be a temporary inconvenience.Potential for Hot SleepingWhile the AS2 is a mattress that I personally slept very cool on, some extremely hot sleepers might still find it retains more heat than they’d like. Despite its open-cell structure and advanced cover, the all-foam design may not dissipate heat as effectively as innerspring or hybrid models for some sleepers.What Other Customers Are SayingNow as thorough as I try to be in my reviews, I am but one woman, with a specific body type and set of sleep issues. I cannot possibly speak to the perspectives and concerns of everyone, no matter how much I wish to. And that’s where other reviews come into play, broadening my understanding of a mattress and its strengths and weaknesses.Now, the AS2 boasts an impressive 4.7 out of 5 stars, with 97% of respondents recommending it to a friend. This high level of satisfaction is noteworthy in the mattress industry, where personal preferences can vary widely. It suggests that the AS2 has broad appeal and is likely to satisfy a large percentage of sleepers.Many reviewers praise the AS2 for its firm yet comfortable feel. As a mattress tester, I know how crucial this balance is. One user described it as “firm but soft,” which aligns with my own experience of the AS2’s Bio-Pur foam providing a supportive surface with just enough give to prevent pressure points.Several back pain sufferers also reported significant improvement after switching to the AS2. One reviewer noted, “I used to have really sore lower back in the mornings when I would wake up. This has gone and I blame the mattress!”Numerous long-term users also reported that their AS2 has maintained its shape and support over time. One reviewer who’s had the mattress for 8 years mentioned buying more for guest bedrooms, which is a strong testament to the mattress’s longevity.This aligns with my observations of the high-quality materials and construction. In an industry where many mattresses start to degrade after just a few years, the AS2’s apparent longevity could represent significant value for consumers.While not mentioned as frequently as its support, several users noted that the AS2 sleeps cool. One reviewer who tends to sleep hot reported not having much issue with temperature on this bed. This corroborates my findings that the open-cell structure of the Bio-Pur foam does indeed contribute to better airflow than traditional memory foam.Similarly, a couple of reviewers mentioned not being disturbed by their partner’s movements during the night. It’s good to see that others’ real-world use confirms the AS2’s ability to minimize motion transfer.I find that these user reviews largely confirm my own assessments of the AS2, but they also provide valuable long-term insights that even my rigorous testing can’t replicate. The overwhelmingly positive feedback on support and pain relief suggests that Amerisleep has indeed succeeded in creating a mattress that meets the needs of many sleepers, particularly those seeking a firmer surface.Notable ConsWhile overwhelmingly positive, some reviews did highlight potential drawbacks:Too Firm for Some: A few side sleepers found the AS2 too firm. This isn’t surprising, as side sleepers often prefer softer surfaces. It’s a reminder of why I always recommend considering your primary sleep position when choosing a mattress.Initial Odor: A small number of users noted a lingering scent, with one describing it as “nutty.” In my experience, some off-gassing is common with foam mattresses, but it’s worth noting for those sensitive to smells.Edge Support: One reviewer mentioned difficulty sitting on the bed’s edges. While not a common complaint, it’s a point worth keeping in mind if you have mobility issues.These serve as an important reminder that no single mattress works for everyone. It underscores the importance of considering your individual needs and preferences when choosing a sleep surface.Mattress Policies and PricesWhen shopping for a mattress, understanding the policies and prices is just as crucial as evaluating the comfort and support. These factors can significantly impact your overall satisfaction and the value you receive from your purchase.Overall, I would say that Amerisleep has established itself as a brand that prioritizes customer satisfaction and confidence in their products. This is evident in their generous sleep trial, comprehensive warranty, and transparent pricing strategy.Sleep TrialAmerisleep offers a 100-night free trial for their mattresses, letting you sleep on the mattress at home to see if you like it. If you don’t, you can get your money back.The trial doesn’t start right away. It begins when your mattress arrives at your home. If you ordered an adjustable bed too, the trial starts when both the mattress and bed arrive.Now, Amerisleep wants you to give the mattress a fair chance. They say it might take up to 30 nights for your body to get used to the new mattress. If you feel a little sore at first, that’s normal and should go away soon.If you decide you don’t like the mattress, you need to contact Amerisleep within the 100 nights. But they ask that you try the mattress for at least 30 nights before deciding to return it.Returning the mattress is also easy. See, Amerisleep will send someone to pick up the mattress for free. You don’t have to ship it back yourself. Once the mattress is picked up, Amerisleep will give you your money back.You also don’t need to keep the box or any packaging to return the mattress. Amerisleep does ask that you recycle as much of the packaging as you can, to help the environment.WarrantyAmerisleep offers a 20-year warranty on their memory foam and hybrid mattresses. The warranty is split into two parts. For the first 10 years, Amerisleep will replace your mattress for free if it has defects. In the next 10 years, you’ll have to pay part of the cost to replace a defective mattress.The warranty covers problems caused by poor workmanship. This includes cracks in the foam and broken zippers on the cover. It also covers sagging greater than 1.5 inches in the middle of the mattress.The warranty doesn’t cover normal wear and tear. This means it won’t cover the mattress getting softer over time. It also won’t cover damage you cause to the mattress.To keep your warranty valid, you need to use the right type of bed frame or foundation. You also need to keep the law tag on the mattress and avoid staining it. Using a mattress protector is a good idea to prevent stains.If you need to make a warranty claim, you’ll need to show proof that you bought the mattress. You might also need to send photos of your bed frame to show you’re using the right support.Remember, this warranty is only for the person who originally bought the mattress. If you give the mattress away or sell it, the warranty doesn’t transfer to the new owner.Sizes and PricesI would say that the Amerisleep AS2 is positioned as a premium product in the mid-range market. Its pricing reflects the quality of materials used and the specific technologies in its design. While it’s not the cheapest option available, it offers good value and is available in all standard mattress sizes.Amerisleep AS2 SizeMattress PriceTwin Size$799Twin XL Size$849Full Size$999Queen Size$1049King Size$1349California King Size$1349Split King Size$1748As always, the best value will depend on individual needs, preferences, and budget constraints.When we consider the price-to-feature ratio, the AS2 sits in a competitive spot in the market. It’s priced higher than budget-friendly options like Tuft & Needle, Vaya, and Bear, but offers more advanced features.It’s also significantly less expensive than premium brands like Tempur-Pedic and Saatva, while still offering high-quality materials and construction. Overall, I would say it’s priced most similarly to popular mid-range options like Casper, with comparable quality but different feel and features.And remember, mattress prices often fluctuate due to sales and promotions, so it’s worth keeping an eye out for deals that could make the AS2 even more competitive in its price point.Caring for Your MattressI’ve become something of a mattress whisperer after years of testing countless mattresses (and yes, my back has stories to tell), and I know that you have to take care of your mattress if you want it to return the favor every night.Treat it right with some occasional special routines, and it’ll be there for you through thick and thin, firm and plush, sweet dreams and insomnia-fueled sheep counting sessions.Have a Mattress ProtectorA waterproof mattress protector shields against spills, stains, and the dreaded dust mite invasion. Plus, it’s much easier to wash than trying to stuff your entire mattress into the washing machine (please don’t try this at home).As someone who sneezes non-stop when pollen is in the air, I also strongly recommend a mattress protector as a way to keep outside irritants from settling on your mattress.Rotating the MattressWhile the AS2 doesn’t need flipping due to its layered construction, I recommend rotating it 180 degrees every 3-6 months. This promotes even wear and prevents body impressions from forming in one spot.I usually find that after rotating a mattress, the areas that had started to feel slightly softer (where I usually sleep) even out within a few nights.Cleaning the MattressRegular vacuuming helps maintain the AS2’s cleanliness and keeps the dust bunny population in check. Be gentle and use the upholstery attachment of your vacuum cleaner. The mattress doesn’t respond well to the “pet hair tornado” attachment, trust me.Try to vacuum the entire surface at least once a month. Consider it a spa day for your mattress, minus a couple of cucumber slices.Pay extra attention to seams and crevices. These are the dust bunny equivalent of five-star resorts, providing plenty of room to hide away from the world.If you accidentally spill something on your AS2 (we’ve all been there with the midnight snack mishaps), blot the area immediately. For deeper cleaning, use a mild detergent mixed with cool water. Gently dab the stained area. Remember, you’re cleaning a mattress, not kneading dough for a sourdough starter.Allow the spot to air dry completely. Resist any urge to use a hair dryer—your mattress doesn’t need a blowout.Smell the BedOccasionally, take a good whiff of the AS2. You don’t have to press your face into the bed, just sniff above the surface to see if anything’s off. If you detect notes of a sweaty night or lingering flatulence, it’s time for action to freshen up the mattress.Sprinkle some baking soda over the surface (not the whole box, we’re deodorizing, not baking a giant mattress cookie). Let it sit for a few hours, then vacuum it up. Your AS2 will smell as fresh as the day it was unboxed, minus that new mattress smell that made you question your life choices for a week.Give It Fresh AirEvery now and then, strip your AS2 down to its essentials and let it breathe. Open the windows, let the fresh air in, but keep it out of direct sunlight. UV rays are great for your plants, not so much for your mattress materials.Frequently Asked Questions Do you need a firmer mattress as you age?As we get older, our bodies may require more support to maintain proper spinal alignment and reduce pressure points, which can sometimes be achieved with a firmer mattress. For back and stomach sleepers, or those with higher body weight, firmer memory foam often offers the necessary support without excessive sinking.But it is not a one-size-fits-all rule. The best firmness also depends on factors such as body weight, sleep position, and personal comfort preferences, which can change with age.Some older adults may find that a medium-firm mattress, like the AS2, provides a good balance of support and comfort, while others might prefer a softer or firmer surface. Is a foam or spring mattress better for back pain?Both can be beneficial for back pain, but their effectiveness depends on the specific design and the individual’s needs. Foam mattresses, especially those with memory foam like the AS2, can provide excellent pressure relief and contouring, which can help alleviate back pain by distributing body weight evenly.Spring mattresses, particularly those with pocketed coils, offer responsive support and can be good for maintaining proper spinal alignment. Ultimately, the best choice often comes down to personal comfort and the specific characteristics of the mattress, rather than simply a question of foam versus spring. Is the Amerisleep AS2 good for side sleepers?It may not be the ideal choice for all side sleepers, especially those who prefer a softer surface. As a medium-firm mattress, it can potentially create pressure points at the shoulders and hips for some side sleepers, particularly those with lighter body weights.However, the HIVE® technology in the AS2 does provide zoned support that offers more give in the shoulder and hip areas, which can benefit some side sleepers. For side sleepers who prefer a firmer feel or those who alternate between side and back sleeping, the AS2 could still be a good option. Who should not sleep on the AS2?It may not be the best choice for exclusive side sleepers, especially those with lighter body weights, as its feel might create pressure points at the shoulders and hips. Those who prefer a very soft sleeping surface might find the AS2 too firm for their liking.Additionally, those with specific medical conditions that require a specialized sleep surface should consult with their healthcare provider before choosing the AS2 or any mattress.Lastly, sleepers who tend to sleep hot and are not satisfied with the cooling properties of foam mattresses might prefer a hybrid or innerspring option instead. How do I know if my mattress is causing my back pain?Pay attention to several key factors. First, notice if your back pain is most intense when you wake up but tends to improve as you move around during the day. This is often a sign that your sleeping surface may be the culprit.If you find yourself tossing and turning frequently throughout the night, or if you wake up with noticeable pressure points or numbness in certain areas of your body, these can also indicate that your mattress isn’t providing proper support.Another telling sign is the age and condition of your mattress. If your mattress is more than 7-10 years old, shows visible sagging, or has lost its original shape and support, it’s likely contributing to your back pain.You might also try sleeping on a different surface, like a guest bed or a high-quality hotel mattress, for a few nights to see if your back pain improves—this can help isolate your regular mattress as the source of the problem.Remember, while a poor mattress can certainly cause or exacerbate back pain, it’s always advisable to consult with a healthcare professional to rule out any underlying medical conditions that might be contributing to your discomfort.ConclusionAfter thoroughly testing and analyzing the Amerisleep AS2, it’s clear that this is a standout product in the competitive world of sleep solutions. With an impressive overall score of 9 out of 10, the AS2 demonstrates excellence across multiple key performance areas.What sets the AS2 apart is its thoughtful construction. The Bio-Pur® foam offers a responsive and cooling sleep surface, while the HIVE® technology provides zoned support that adapts to different body parts. This combination results in a mattress that excels in pressure relief and spinal alignment, particularly benefiting back and stomach sleepers.However, it’s important to note that no mattress is perfect for everyone. Side sleepers, especially those of lighter weight, might find the AS2 a bit too firm. Additionally, the price point, while justified by the quality and features, may be a consideration for budget-conscious shoppers.But if you fall within the AS2’s target audience and your savings allow you to invest, this mattress could be your ticket to significantly improved sleep quality and overall well-being.Final Score TallyThicknessPerformanceExplanation10 InchesGood for sleepers who prefer a firmer, more responsive feel.A 10-inch latex mattress tends to feel firmer and more buoyant, offering excellent support and durability.12 InchesBetter for side sleepers and heavier individuals who need more pressure relief.The additional thickness provides more cushion and comfort, especially for those who need extra pressure relief at key points like the hips and shoulders.
