Amerisleep AS5 Hybrid Mattress Review (2026)

Why Trust Best Mattress Brand

Every mattress we recommend is tested hands-on by Sarah Anderson, our Certified Sleep Coach and Mattress Tester, who has personally tested 43+ mattresses using our mattress testing methodology. Each guide is scored on the same fixed measures and cites only credible sources, and our health-related content is reviewed by an independent board of sleep and medical experts. As products change, we re-test them so our recommendations reflect the current version of each bed.

I tested the Amerisleep AS5 Hybrid as a soft hybrid rather than judging it by the promises attached to its materials. The first thing I noticed was how far the comfort layers allowed my shoulder to settle when I moved onto my side. The coil system underneath kept that softness from turning into a flat, unsupported feel.

The mattress also behaved differently from a dense all-foam soft bed when I changed positions. I could roll from side to back without feeling trapped, although the plush surface was not as quick to reset as the most responsive hybrids I have tested. That result is reflected in its 8/10 Response Time score.

Cooling was the strongest performance area. The cover felt cool to my hand at first contact, and the surface did not hold as much warmth after a short lying test as the denser foam beds I use for comparison. The rest of this review breaks down who this very soft feel suits, where it falls short, and whether its current price makes sense for your priorities.

Inside the Amerisleep AS5 Hybrid: Materials and Construction

The AS5 Hybrid is a 14-inch soft hybrid built from 3 inches of Bio-Pur memory foam, 2 inches of Active Flex foam, 8 inches of zoned pocketed coils, and a 1-inch durable base foam. I am listing the layers here only where they explain something I observed in testing.

Refresh Cooling Cover

The Refresh cover was the first part I could verify directly. It felt cool to my hand on first contact, and the same area did not hold as much warmth after a short lying test as the denser foam surfaces I have compared. That observed temperature behavior is the useful testing result here.

3-Inch Bio-Pur Comfort Layer

This layer produced most of the deep contouring I felt on my side. My shoulder and hip settled farther into the surface than they do on medium Amerisleep models. The foam also recovered after I removed hand pressure, which contributed to the mattress remaining movable despite the soft feel.

2-Inch Active Flex Layer

Active Flex sits between the comfort foam and the coil system. In testing, the useful effect was that the surface did not remain compressed after I shifted positions. It added some rebound under the deeper Bio-Pur contour, although the complete mattress still scored 8/10 for Response Time because the plush build is not as quick as the fastest hybrids.

8-Inch Zoned Pocketed Coils

The coil core was most noticeable in edge, motion, and position testing. I felt stable sitting and lying near the perimeter, and most partner movement stayed localized rather than traveling across the full surface. The open space around the coils also gives the mattress a more breathable support structure than a solid foam core.

1-Inch Durable Base Foam

The base foam sits beneath the coil unit and stabilizes the support system. It is not a comfort layer I could isolate by feel, so I am not assigning it a separate performance benefit beyond supporting the coil assembly.

The mattress uses CertiPUR-US certified foam, a certification that includes testing for low VOC emissions. I treat that as a materials certification rather than evidence of a broader health or safety outcome.

Setup Observation

The mattress arrived compressed. It began expanding after the plastic was removed, and the existing test record notes only a faint initial odor rather than a strong smell. The 14-inch build is heavy enough that having another person available for setup is practical.

Testing Sleeping Positions

Side Sleeping

Side sleeping was the strongest fit for the AS5 Hybrid. I lay on my side in several areas of the mattress and paid attention to how far my shoulder and hip settled relative to my waist. The soft comfort layers gave those pressure-bearing areas more room to sink, while the coil support underneath kept the middle of my body from dropping through the surface. This is the position that best matches the mattress’s very soft feel.

Back Sleeping

On my back, the AS5 Hybrid filled the space around my lower back and gave me more contouring than a medium hybrid. I could still feel the support core holding me up under the comfort layers, but the surface is deliberately plush. Back sleepers who prefer a cushioned feel can enjoy it, while people who want a flatter, firmer surface should compare a firmer model.

Stomach Sleeping

Stomach sleeping exposed the main fit limitation. The AS5 Hybrid is soft enough that the midsection settles more deeply than it does on the firmer hybrids I prefer for this position. I could lie on it for testing, but I would not choose it for a strict stomach sleeper who needs a more level, lifted surface through the hips and abdomen.

Combination Sleeping

I changed from side to back and back to stomach repeatedly to see whether the plush top made movement feel restricted. The coils and Active Flex layer helped me move without feeling trapped, but the deep contouring still made transitions slower than on firmer, more buoyant hybrids. That is consistent with the 8/10 Response Time score rather than a top-tier responsiveness result.

Response Time

Response Time matters most when you change positions because a surface that recovers slowly can make a plush mattress feel harder to move through. The AS5 Hybrid is softer than most hybrids I test, so I checked whether that extra contouring created a stuck feeling.

I pressed my hand firmly into several parts of the surface and watched the foam recover after I lifted it. I also rolled from my back to my side and then to my stomach, and I used the existing 10-pound ball-drop test to check how much rebound the surface produced. The comfort layers recovered quickly after the hand press, and the coil system added noticeable bounce.

During full-body position changes, though, the deep plush surface took more effort to move through than the quickest hybrids I have tested. I did not feel trapped, but sleepers who want a very fast, buoyant surface can find firmer hybrids easier to reposition on.

Motion Transfer

Motion Transfer matters most for couples, especially when one sleeper changes positions or gets out of bed earlier than the other. I tested the AS5 Hybrid with both a partner and a weighted-object setup rather than judging it from the coil design alone.

My partner moved, changed positions, and got in and out of bed while I stayed still on the opposite side. I also dropped a weighted object on one side and watched how much movement reached the other side. Most movement stayed close to where it started, and I felt only limited transfer during ordinary position changes.

The soft foam layers absorb a meaningful amount of movement before it reaches the coil unit, while the individually wrapped coils move more independently than a connected spring system. That combination makes the AS5 Hybrid a strong fit for couples who want plush cushioning without a highly active surface.

Edge Support

Edge Support determines how usable the mattress feels near the perimeter and how stable it feels when you sit down to get in or out of bed. This is especially important on a very soft mattress because deep comfort layers can compress under concentrated weight.

I sat on the perimeter with my feet on the floor and then lay close to the edge to compare the outer area with the center. The edge stayed stable enough that I did not feel as if I were sliding off, and I could lie near the perimeter without a strong roll-off sensation.

I did not record a measured compression figure, so I am not treating the perimeter as a perfect result. The edge still felt stable for a soft hybrid, and I could use the outer portion of the mattress without a strong roll-off sensation.

Cooling & Breathability

Cooling & Breathability matters because thick, soft comfort layers can hold more body heat than thinner or firmer surfaces. I checked the AS5 Hybrid by touching the cover before use, lying on one area for about 15 minutes, and noting the surface temperature again after I moved.

The Refresh cover felt cool on first contact. After the lying test, the area I had occupied did not feel as warm as the dense foam surfaces I use for comparison. I also spent multiple test nights on the mattress and did not record heat buildup that forced me to move away from the area I was sleeping on.

The open-cell foam and space around the pocketed coils provide a plausible airflow path, but the 10/10 score is based on the observed temperature behavior in testing, not on a manufacturer promise.

Durability and Expected Lifespan

A short mattress test cannot prove how the AS5 Hybrid will feel after years of nightly use, so I am not assigning it a lifespan from a few weeks of observation. What I can report is how the materials behaved during the current test and what Amerisleep’s warranty covers.

The comfort layers recovered after repeated hand pressure and position changes, and the perimeter remained stable through repeated sitting and lying tests. I did not record a lasting impression during the test period. Those observations are useful, but they are not a substitute for multi-year wear data.

Amerisleep backs the mattress with a 20-year limited warranty. Covered sagging must exceed 1.5 inches, and support-system requirements apply. I would use those terms as the ownership reference point rather than promising a specific number of usable years.

Pros and Cons

Pros

• Cooling & Breathability (10/10): the cover felt cool on first contact, and the surface held less warmth after my short lying test than the dense foam beds I compared.
• Motion Transfer (9/10): most partner movement stayed localized during opposite-side testing, which is a strong result for a soft hybrid.
• Side-sleeper fit: the comfort layers gave my shoulder and hip enough room to settle while the coil core kept the mattress from feeling flat underneath me.

Cons

• Response Time (8/10): I could change positions without feeling trapped, but the deep plush surface moved more slowly than the quickest, firmer hybrids I have tested.
• Value (8/10): even with current promotional pricing, this is a premium-priced soft hybrid, so budget-focused shoppers have stronger value options.
• Firmness fit: the 3/10 feel is too soft for many strict stomach sleepers and anyone who prefers a more level, lifted sleep surface.

Common Complaints and What I Found

Every mattress has a few complaints that come up repeatedly from owners. Here are the recurring concerns around the AS5 Hybrid and what I found when I tested them myself.

The soft feel can take time to adjust to. A recurring owner theme is that the AS5 Hybrid’s very soft feel can take time to get used to. I did not need a long break-in period during testing, but I noticed substantially deeper contouring than on a medium mattress. That difference is most likely to affect sleepers moving from a firmer bed.

It can feel too soft for some sleepers. This complaint is consistent with the mattress’s actual 3 out of 10 firmness. Side sleeping was the clearest match in my test. During stomach testing, my midsection settled more deeply than I prefer, so strict stomach sleepers and people who want a flatter surface are the most likely to notice this tradeoff.

There can be an initial odor. My test notes recorded a faint initial smell after unboxing rather than a strong odor. I would treat that as a setup issue rather than a long-term performance problem. Anyone sensitive to new-product odors may prefer to give the mattress some ventilation time before adding bedding.

Some owners say soft beds sleep warm. That concern did not match my test result on this model. Cooling & Breathability scored 10 out of 10: the cover felt cool at first contact, and the surface retained less warmth after a short lying test than the denser foam beds I compared. That result does not guarantee every sleeper will experience the same temperature.

Consider Instead

• Saatva Classic if you want a firmer, more lifted surface with stronger response and more firmness choice.
• Helix Midnight Luxe if you are a side sleeper who wants cushioning but does not want a 3 out of 10 ultra-soft feel.
• Best Soft Mattress if you want to compare this model with other soft beds before choosing.

Mattress Policies and Prices

Sleep Trial

Amerisleep includes a 100-night mattress trial. The company asks customers to keep the mattress for the first 30 nights before starting a return. Eligible mattress returns are handled with pickup and a refund under Amerisleep’s current trial terms. Trial Period Score: 9/10.

Warranty

The AS5 Hybrid carries a 20-year limited warranty for the original purchaser. During the first 10 years, Amerisleep may repair or replace a mattress with a qualifying defect. Amerisleep covers the repair or replacement itself, while labor and transportation are not covered and cover-related costs may apply. During years 11 through 20, a qualifying replacement costs 50% of the original purchase price, plus applicable shipping, cover-replacement, and labor costs. Covered indentations must be greater than 1.5 inches and cannot result from an inadequate support system.

Shipping

Mattress shipping is free within the continental United States. Amerisleep ships the mattress compressed by FedEx. Orders containing other sleep products may arrive in separate shipments.

Value

The AS5 Hybrid earned 8/10 for Value. Its current price places it in the premium end of the soft-hybrid market, so the strongest reason to pay more is the specific combination of deep cushioning, a coil support system, 9/10 Motion Transfer, and 10/10 Cooling & Breathability rather than price alone.

Sizes and Prices

Amerisleep is running a $600 promotion across sizes at the time of writing.

Prices confirmed against the Amerisleep product page on August 18, 2026. Shipping and returns are free within the continental US. Value scored 8 out of 10: the AS5 Hybrid remains a premium-priced mattress, but its deep plush feel, hybrid support system, cooling performance, and motion control add value for sleepers specifically looking for a very soft hybrid.

Care and Setup

Use the AS5 Hybrid on a solid non-spring foundation, compatible platform bed, adjustable base, or qualifying slatted frame. If the slatted base is not sold by Amerisleep, the slats must be no more than 2.75 inches apart. A box spring requires a 0.75-inch moisture-resistant plywood sheet across the full surface to meet Amerisleep’s support requirement.

Amerisleep’s current care guidance says the mattress does not need to be flipped or rotated. Keep the white cover side facing up. Because the AS5 Hybrid is 14 inches tall, confirm that fitted sheets have enough pocket depth before purchase.

Conclusion

The Amerisleep AS5 Hybrid finished with an 8.8 out of 10 Overall Score. Its strongest result was Cooling & Breathability at 10/10, followed by 9/10 scores for Edge Support, Trial Period, and Motion Transfer. The two areas that kept it below the very top of the scale were Value and Response Time, both at 8/10.

What stood out most in my test was the side-sleeping fit. My shoulder and hip could settle into the plush top while the coil system kept the mattress from feeling flat underneath me. I also found the perimeter stable enough to sit and lie near the edge without a strong roll-off sensation. During partner testing, most ordinary movement stayed close to where it started.

The tradeoff is the same quality that makes the mattress appealing: it is very soft. The 3/10 feel and deep contouring are not ideal for strict stomach sleepers or anyone who wants a flatter, faster surface. Its premium price also makes fit more important than features alone.

I recommend the AS5 Hybrid most strongly to side sleepers and soft-mattress shoppers who prioritize cushioning, cooling, and motion control. Firmer-surface shoppers should use the Consider Instead section before buying.
