Why Trust Best Mattress Brand Caret Down Our proficient team of sleep science coaches, engineers, and product evaluators rigorously inspect hundreds of mattresses using our unique product methodology. Each article is scrutinized for precision, citing only credible sources. Systematically reviewing our content and recommendations, we align with the latest scientific literature and expert insights. Our top-rated mattresses have been personally evaluated and highly rated. How We Test Caret Down When testing our mattresses we evaluate several key factors that people take into consideration when choosing between mattresses. First is performance in each sleeping position. We test each mattress in the back, side, and stomach sleeping positions to note how the mattresses perform for different sleeping types. Next, we test response time to note how quickly the mattress responds to movements - this metric is important for those that shift positions throughout the night. Next is Motion Transfer - this test is important for couples. We note how much motion is felt on one side of the mattresses when there's movement on the other. If you're sharing a bed, you want minimal motion transfer so that if your partner moves during the night it doesn't wake you up. We also test edge support to see how sturdy the edge of the mattress is. We note how well supported you are when sitting and laying near the edge of the mattress. And last we test cooling and breathability by noting how cool to the touch the mattress cover is and also how breathable the materials are to ensure you don't sleep hot. Fiberglass is an all-too-common material used in mattresses. While non-toxic, fiberglass still causes skin, eyes, mouth, and throat irritation. This only makes it harder to sleep.

The glass fibers may be randomly woven, flattened into a durable sheet, or woven into cloth. It’s cheap and easy to produce, yet still extremely durable and non-toxic.Get resources for better sleepSign up for sleep health education, expert tips, and the latest and greatest mattress sales. Email See Privacy PolicyWhy Do Mattresses Contain Fiberglass?As per the US’s federal regulations for health and safety, mattresses must contain some sort of flame retardant or fire barrier. This way, in case of a fire, your mattress doesn’t immediately catch into flames and a person can escape safely. Without a proper flame barrier, sleepers are at risk of injury or even death. The NIST says these standards have saved lives.When mattress mandates originated, chemical flame barriers were an acceptable fire retardant. However, they were quickly banned after they turned out to contain harmful chemicals and be toxic to humans. So, mattress manufacturers now needed to use chemical-free flame retardants, thus came the rise of fiberglass.Fiberglass is common in memory foam and polyurethane mattresses but can be found in any type of bed. In the event of a fire, the fiberglass would melt and encapsulate the mattress so it doesn’t burn and the fire doesn’t spread.Why Should You Avoid Mattresses With Fiberglass?Exposure to fiberglass particles can cause issues such as skin irritation, redness, and rashes. You may also experience eye irritation and redness, stomach pain, nausea, and a sore throat or mouth.The side effects of fiberglass exposure are almost always short-term and there is no evidence suggesting it causes long-term damage to your health. Regardless, skin, eye, mouth, and throat irritation is uncomfortable and affects your breathing.While beds with fiberglass are often cheaper than beds without fiberglass, your health and sleep quality will improve by getting a fiberglass-free bed. The best mattress for your health shouldn’t contain fiberglass to prevent irritation.What Other Flame Barriers Are There?Although fiberglass isn’t deadly or harmful long-term, lots of people want to avoid it for obvious reasons. There are healthier, more natural alternatives that protect your bed in the event of a fire without irritating your body.Try looking for beds containing:WoolPlant fibersSilicaEco-friendly, organic, and generally sustainable mattresses are more likely to contain these flame retardants instead of fiberglass.Since being an eco-friendly mattress doesn’t guarantee that your bed is fiberglass-free, check the bed’s third-party certifications. Third-party organizations inspect a bed’s materials and production process to ensure it’s free of fiberglass amongst other chemicals.Third-party certifications to look for in a mattress include:CertiPUR-US® Global Organic Latex Standard (GOLS)Global Organic Textile Standard (GOTS)OEKO-TEX®Rainforest Allianceeco-Institut® Greenguard GOLDMADE SAFE®Mattresses will almost never have all of these certifications, especially because certain certifications are only relevant to certain types of materials. Most types of mattresses only have several of these certifications at best, which is completely acceptable.SEE ALSO: The Best Place to Buy a Mattress & 7 In-Store MythsTypes of MattressesThere are several types of mattresses available on the market, each with its own unique features and benefits. Four popular mattress types are memory foam, latex, innerspring, and hybrids.1. Memory Foam MattressesMemory foam mattresses are made from a high-density foam that conforms to the shape of your body, providing excellent pressure relief and support. Most memory foam mattresses are known for the way they hug the body, easing pressure and pains. These mattresses are also known for their motion isolation properties, making them a great option for couples.2. Latex Mattresses Latex mattresses are made from natural or synthetic rubber and are known for their durability and responsiveness. Such natural latex mattresses are also hypoallergenic and resistant to mold and dust mites, making them a great option for people with allergies.3. Innerspring MattressesInnerspring mattresses are made with a steel coil support system that provides a traditional feel and bounce. These mattresses are often more affordable than other types. However, some sleepers, particularly side sleepers, may find that innerspring mattresses don’t relieve enough pressure.4. Hybrid MattressesHybrid mattresses combine the benefits of memory foam or latex with the support of an innerspring system. These mattresses typically have a layer of foam on top for comfort and pressure relief, with an innerspring system for support and durability.Mattress Firmness for Different Sleeping Positions1. Side SleepersFor side sleepers, a medium to soft mattress is ideal. This is because they need a mattress for side sleeping that can distribute their body weight evenly, especially around the shoulders and hips. If a mattress is too firm, it can create pressure points on these areas, leading to discomfort and even pain.2. Back SleepersBack sleepers need a mattress that is medium-firm to firm. This is because they need a mattress for back sleeping that can support their spine’s natural curvature while keeping their body in proper alignment. A medium-firm to firm mattress can help prevent the lower back from sinking too much into the bed, which can cause discomfort and pain over time.3. Stomach SleepersFor stomach sleepers, a firm mattress is best. This is because they need a mattress for stomach sleeping that can keep their hips from sinking too far into the bed, which can cause the spine to become misaligned. A firm mattress can provide the necessary support to keep the spine in proper alignment while also preventing discomfort and pain.Combo SleepersCombo sleepers need a mattress that can accommodate different sleeping positions. A medium to medium firm mattress is usually best for combo sleepers. Such mattresses for combination sleeping can provide the necessary support for back and stomach sleeping while also being soft enough to accommodate side sleeping. A hybrid mattress, which combines different materials like foam and coils, can be an excellent option for combo sleepers as it can provide the best of both worlds in terms of support and comfort.A Quick Look at Mattress Brands & Fiberglass UseIt takes time to sort through reviews and research to find mattresses free of fiberglass.

When avoiding beds with fiberglass, look for beds that contain safer fiberglass alternatives such as wool, silica, or plant fibers. Your best bet is to shop for organic, eco-friendly, and latex beds as they are commonly fiberglass-free, but any bed can be fiberglass-free.How do I know if my mattress has fiberglass?Some (but not all) mattress companies will clearly promote their beds as being fiberglass-free and containing a different flame barrier.If it’s unclear whether or not your bed contains fiberglass, check the tag or specifications online. Look for keywords such as “particle glass,” “glass fibers,” or simply “fiberglass.”Check to see if your mattress’s label says “do not remove cover.” Some mattress covers may have zippers and still have this label, but that likely means the zipper was added to simplify the manufacturing process. Mattress labels say not to remove the cover because there is likely fiberglass beneath it and removing it can cause fiberglass to spread through your room.What mattresses don’t contain fiberglass?Technically, any type of mattress can be fiberglass-free. Certain types of beds are simply more or less likely to contain fiberglass. Organic latex mattresses and natural latex mattresses are most likely to be fiberglass-free and instead contain wool or silica.Conversely, memory foam and polyfoam mattresses are more likely to contain fiberglass. If these types of mattresses intrigue you, double-check the bed’s specifications to ensure it’s fiberglass-free.Are there memory foam mattresses without fiberglass?Yes, you can find memory foam mattresses without fiberglass, though they’re less common than latex beds without fiberglass. While uncommon, it’s still not impossible.Some of the best memory foam mattresses without fiberglass are the Zoma Start and the Amerisleep AS3.Can fiberglass cause health problems?According to the CDC, fiberglass exposure can cause irritation to the skin, nose, mouth, and throat. Additionally, fiberglass can lead to red, itchy eyes, stomach pain, skin rashes, and a sore throat.A common misconception with fiberglass is that it can cause long-term respiratory issues and even cancer, but no evidence supports this claim. Fiberglass symptoms are usually only present when you’re in contact with it but go away once you’re no longer in contact with the fiberglass.ConclusionFiberglass isn’t deadly or harmful long-term, but it’s still uncomfortable and irritating when in contact with it. Also, it makes a big mess if it ever gets out from under your mattress’s cover.
