In recent years, there has been a growing awareness about the materials used in mattresses, particularly regarding the potential risks of fiberglass. Fiberglass has long been used as a fire retardant in many mattresses, but growing health concerns have led many manufacturers to seek safer alternatives. When a mattress containing fiberglass is damaged or mishandled, it can release tiny fiberglass particles that pose serious risks. These microscopic shards can irritate the skin, eyes, and lungs, leading to discomfort such as itching, coughing, allergic reactions, and even breathing problems.
For this reason, many sleepers are now switching to fiberglass-free alternatives for peace of mind and better sleep quality. Fiberglass-free mattresses meet fire safety standards without using any potentially harmful materials. These mattresses typically feature safer, non-toxic fire retardant options, such as wool or natural fibers.
Dr. Raj Dasgupta, Sleepopolis’ Chief Medical Advisor, explains: “Exposure to fiberglass can irritate your skin, eyes, and lungs, causing issues like itching, coughing, allergic reactions and even breathing difficulties.” With the increasing number of consumers concerned about fiberglass exposure, choosing a mattress that is free from this material is a wise decision for anyone looking to reduce health risks while still enjoying a comfortable night’s sleep.
As more folks switch to fiberglass-free mattresses, it’s important to know which models offer safe and effective alternatives. In this roundup, I’ll highlight the best fiberglass-free beds for all types of sleepers. Throughout 2024, Sleepopolis helped over 12,500 people find the right mattress, and I’m here to guide you through the process. I’ll provide detailed reviews, share testing results, and explore other mattress features so you can find the perfect fiberglass-free option for your needs.

Best Overall Mattress – Bear Original
Even though it’s made entirely of foam, the Bear has a firm, supportive feel that should be sturdy enough for back sleepers and stomach sleepers alike. Additionally, combination sleepers should be able to easily move around on its surface. You can also pay extra for a Celliant cover that may help with cooling and muscle recovery. Learn more in our video review.
What our tester says:
“I found the double poly foam construction produced a firm, supportive feel. Though you’re likely to sink into its top layer of memory foam, this sinkage is somewhat curbed by the taut poly foam transition layer. This means most folks are going to be positioned more “on top” of the structure than “in” it.” – Nichole Mondshein, lead reviewer and mattress tester
Expert Opinion
The Bear Original is one of the only mattresses made specifically with athletes in mind. The secret? Celliant material in the cover. Studies show that it can help with active recovery by promoting blood flow and oxygen to your tissues. While Sleepopolis cannot personally say if this cover helps with athletes’ recovery time, we can attest to the cooling tendencies. Celliant helps to regulate your temperature, which is great for hot sleepers, or couples who have double the body heat in one bed. However, we do want to be honest with our customers and share that this cover is not included in the overall price of the Bear Original. It must be added at check out for an additional $130.
Best Mattress for Back Sleepers – Helix Midnight Luxe
Helix has a line of six hybrid mattresses, each with a different level of firmness. The Midnight is one of their medium models. It has enough contouring for side sleepers, but should still be supportive enough for back sleepers, as long as they don’t mind a softer bed. Learn more in our video review.
What our tester says:
“I like the Helix Midnight Luxe for back sleepers and side sleepers. The medium-soft to medium-firm feel should give these folks the right balance of comfort and support.” – Nichole Mondshein, lead reviewer and mattress tester
Expert Opinion
The Helix Midnight Luxe is a hybrid mattress that features plush memory foam constructed over pocketed coils for a balance of pressure relief and support. This combination creates a medium-soft to medium-firm feel in the Helix Midnight Luxe that is especially important for both back and side sleepers. These sleepers need enough support to keep their spine in a neutral alignment. Luckily for them, the Helix Midnight Luxe includes an entire support layer of individually wrapped coils. This gives the mattress enough durability to keep sleepers lifted during the night.
Best Hybrid Mattress – Bear Elite Hybrid
The Bear Elite Hybrid uses foam and coils for a mix of support, cushioning, and cooling. While designed for athletes prioritizing wellness and recovery, sleepers of all activity levels can enjoy the many luxurious features. Enjoy zoned support for targeted relief, an “on top of” feel allowing for ease of movement, and cooling features throughout. For more information, watch our video review.
What our tester says:
“I’d recommend the Bear Elite Hybrid for most back and stomach sleepers.I think these sleepers will get the needed pressure relief and contouring around the lower back and hips. This mattress does a wonderful job at offering body contouring while still helping the sleeper stay elevated and lifted as well. The layers of foam should provide comfort while the coil system should offer lots of support.” – Nichole Mondshein, lead reviewer and mattress tester
Expert Opinion
Hybrid models have become really popular since their blend of materials offers the sought-after combination of support and pressure relief. When we tested out the fiberglass-free Bear Elite Hybrid — made with soft memory foam up top and sturdy coils at the bottom — we experienced all of the features that hybrids are known for: spinal support, a little bit of contouring, and plenty of cooling. We found it to be on the softer end, giving it a score of 6 out of 10 on our mattress firmness scale. That means the Bear Elite Hybrid is a bit plusher than most other beds, as the industry standard is set at 6.5 for a medium-firm mattress.
Best Mattress for Stomach Sleepers – Helix Dawn
The Helix Dawn is one of the firmest mattresses offered by the company. Its construction provides good comfort for heavy people and stomach sleepers, both of whom need extra support to keep from sinking uncomfortably below the mattress surface. Like the other Helix mattresses, it can be upgraded to the Luxe version if you’re willing to pay a little extra for luxury features. To learn more, check out our video on Helix mattresses.
What our tester says:
“I really appreciate how supportive these mattresses are. Stomach sleepers, back sleepers, and heavy people (those over 250 pounds) could all benefit from the firm feel of this bed. No matter which model you choose, the Helix Dawn really delivers on lumbar support.” Logan Block, former Sleepopolis content director and mattress tester
Expert Opinion
Stomach sleepers usually require a lot more firmness and support than other sleeping positions. That’s because they put the most pressure on a mattress, and they need a bed strong enough to keep their hips from bowing into the layers and throwing their spine out of alignment. Fortunately, Helix has created a good match for them with the Helix Dawn.
Best Cooling Mattress – Brooklyn Bedding Aurora Luxe
The Brookyn Bedding Aurora Luxe mattress is one of Brooklyn Bedding’s more high-end mattresses. It’s got a ton of cooling features in it that can help hot sleepers sleep cool all night. It’s also available in three different firmnesses, so it can accommodate all of the sleeping positions. For more information, check out our video review.
What our tester says:
“First and foremost, I’d recommend this mattress to hot sleepers. This bed sleeps nice and cool thanks to special phase change technology and gel infusions. The Aurora Luxe is also a nice pick for back sleepers. This mattress in the Medium model is medium-soft, so it should contour the hips while also lifting them into alignment.” – Nichole Mondshein, lead reviewer and staff writer
Expert Opinion
No one wants a mattress that traps heat so easily that they wake up hot and sweaty. During testing, we discovered that the Brooklyn Bedding Aurora Luxe is one of the finest cooling mattresses on the market. It has a cover made with Phase Change Material (PCM), which works to regulate your body temperature. We found that this fabric is quite literally cool to the touch. Beneath is a comfort foam built for pressure relief; this also contains more PCM for even more cooling. The support layer of pocketed coils at the bottom of the mattress allows for plenty of airflow. There’s also an optional Cloud Pillow Top offered for an additional fee, which can be helpful for those who sleep extra hot or those who need a lot of pressure relief.
Best Latex Mattress – Nolah Natural
The Nolah Natural is made with eco-friendly Talalay latex and supportive coils. This mattress has GOTS (Global Organic Textile Standard) organic wool, cotton, natural latex, and recycled steel. The latex makes this mattress responsive, which is great for couples and combination sleepers. This material is also naturally hypoallergenic and cooling, which can help hot sleepers prevent overheating. For more information, watch our video review.
What our tester says:
“It has a very soft, plush feel that provides you some cushioning as well. I’d say you’re going to feel more “on top” of this bed than “in it” — thanks to its bouncy latex.” – Bridget Chapman, former senior product editor.
Expert Opinion
The Nolah Natural is an 11″ mattress made from natural materials, which is especially important for eco-friendly shoppers. This hybrid mattress is hypoallergenic and includes GOTS (Global Organic Textile Standard) certified organic wool, GOTS certified organic cotton, recycled steel, and Talalay latex in its construction. It ranks at a 6 on our firmness scale, making it slightly softer than the industry standard of 6.5 for medium firmness.
Best Organic Mattress – Birch
The Birch Natural is a latex mattress utilizing individually wrapped coils for added support. This mattress specializes in cooling and responsiveness, and the firmer nature suits back and stomach sleepers well. Perhaps the most special part about this mattress is the material quality. Not only is the Birch organic, but it has also earned multiple certifications for safe production and materials. For more information, check out our video review.
What our tester says:
“One of my favorite things about the Birch is how cooling it is. I think any hot sleeper will be satisfied by this breathable bed. It’s definitely one of the most cooling mattresses available thanks to its wool and latex layers. These cooling materials also make it one of my favorite organic mattresses.” – Madison Schaper, Sleepopolis staff writer
Expert Opinion
Helix is known for its original lineup of hybrid mattresses, and they’ve since gotten into the organic game with the Birch. This is an 11-inch tall Talalay latex mattress that ranks at a seven on our firmness scale, making it slightly firmer than the industry standard. This mattress has a highly bouncy feel, which makes it a great pick for combination sleepers who need to be able to move on top of the mattress in order to switch into multiple positions throughout the night. The Birch is also a great mattress for sex because of this bouncy, responsive feel.
Best Firm Mattress – Plank Firm
The Plank Firm more than lives up to its name with its ultra-sturdy foams and supportive feel. While this bed certainly isn’t for everyone, it should be an ideal fit for back sleepers, stomach sleepers, and combination sleepers who want to feel more on top of their mattress than in it. For more information, check out our video review.
What our tester says:
“I think the Plank Firm is one of the best mattresses for stomach sleepers. Both sides of the mattress, the firm side and extra firm side, should give these sleepers the support they need to keep their hips in line with their shoulders. Back sleepers who like a firmer feel should also be happy on the firm side of the Plank.” – Nichole Mondshein, lead reviewer and staff writer
Expert Opinion
You can probably guess from the name alone that the Plank is one of the firmest mattresses out there. Created by Brooklyn Bedding, it’s made entirely of foam and has a flippable design, with both a Firm side and an Extra-Firm side. You can turn it over to see which one is most comfortable for you, or even alternate between sides depending on the night.
Why Do Mattresses have Fiberglass?
The fiberglass that is used in mattresses is a composite material, which are very fine shards of glass. Fiberglass is often used in mattresses as a flame retardant and is meant to be safe, but many people are wary of having it in their beds since it can cause health concerns if exposed.
Because it’s a common and inexpensive material for manufacturers to use commonly in insulation, boat construction, automotive parts, bath tubs, showers, and as a fire barrier in mattresses. One reason to avoid fiberglass in a mattress is the potential for it to break down and become airborne, which can irritate the skin and respiratory system. Additionally, if the mattress is damaged, fiberglass can escape, creating a messy and difficult-to-clean situation.
If you’d like to learn more, please check out our guide on fiberglass for more information.
Hear from the Experts:
What are the Health Risks of Fiberglass Exposure?
“Exposure to fiberglass can irritate your skin, eyes, and lungs, causing issues like itching, coughing, allergic reactions, and even breathing difficulties.”
Dr. Raj Dasgupta, MD, FACP, FCCP, FAASM. Quadruple-board certified in pulmonary, sleep, internal, and critical care medicine
How to Check if Your Mattress has Fiberglass
Although it can be safe if used properly, many consumers are looking to avoid the material altogether. Here are some quick ways to check if a mattress contains fiberglass.
Search for Organic Materials
Companies will often use organic and hypoallergenic materials, like cotton or wool, in the fire barriers of mattresses instead of fiberglass. Be on the lookout for certifications like CertiPUR-US, GOLS Certified (Global Organic Latex), GREENGUARD Gold Certified and more to make sure the mattress materials are organic and up to standard.
Ask the Manufacturer
If it’s not clearly stated on their website, you can ask a mattress company representative via online chat or phone whether or not they use fiberglass in any form in their beds. Fiberglass is also referred to as glass fiber or glass wool sometimes, so make sure the company’s being transparent.
Check the Mattress Label
It’s required for every new bed to have a tag that states all the materials used in it. Most fiberglass-free mattresses will state it clearly on the label and we have made sure to only select beds without fiberglass in this lineup.
Avoid the Cheapest Option if Possible
Of course, budget is a huge factor when selecting a mattress. Since fiberglass is appealing to companies for its low cost, it’s often used in less expensive beds. A good rule of thumb is to double-check the mattress tag. There are several fiberglass-free mattresses out there that will fit the budget. Some affordable fiberglass free brands to look out for includes Bear & Brooklyn Bedding.
What Does a Fiberglass Label Look Like?
If a mattress does contain fiberglass it will have some sort of label on it with terms like “fiberglass,” “glass fiber,” or “glass wool” as a listed material. Also, the mattress label might state “do not remove cover”. Beware that this often means the mattress contains fiberglass and this is a warning about potential fiberglass exposure. Keep in mind that fiberglass is often found is the cover of mattresses, so check for those labels.
What are the Risks of Fiberglass?
Fiberglass isn’t dangerous unless exposed. If a mattress has fiberglass exposed, it could cause skin irritation, respiratory issues and larger issues if exposed for a long time. This often isn’t an issue in mattresses unless you take off the cover which can release those glass particles in your environment. Keep in mind, we have primarily only seen fiberglass in the mattress covers, so be sure to not remove covers unless you know its a fiberglass free mattress like the ones we have picked here. Check out our guide on What you Need to Know about Fiberglass for more information.
What to Consider When Buying the Best Mattress Without Fiberglass
Thanks to some recent high-profile lawsuits, the use of fiberglass in mattresses has made headlines recently. So… is it safe to actually use in mattresses? Yes – but there are a few caveats.
Mattress companies will often use fiberglass as a flame retardant since it meets safety standards and is a cheap option compared to other alternatives. Fiberglass may prevent a mattress from bursting into flames if it catches fire and will lead it to slowly burn instead. However, it’s essential for fiberglass to be completely concealed in a mattress and never be exposed to sleepers. However, if a mattress is poorly made or becomes damaged, the fiberglass may be released. If you’re exposed to fiberglass, it can damage your eyes, skin, upper respiratory tract, and lungs. It’s also very difficult to clean up once it’s released into your environment.
Mattress Types
Although they share the commonality of not containing fiberglass, you may have noticed that we’ve included several different types of beds in this roundup. Let’s go over their differences.
- Foam: All-foam mattresses are made entirely of foam layers and tend to offer great pressure relief. They can be less expensive, but also less durable.
- Innerspring: Innerspring mattresses are a little more “old school” and used to mainly consist of just springs and fabric in their construction. Nowadays, innerspring mattresses usually have a good bit of foam in the construction as well. They tend to be very responsive and supportive.
- Hybrid: A hybrid mattress is built with a combination of different materials — usually foam and coils. They’ve become very popular in the mattress market since they often have a balanced, medium-firm feel.
- Latex: A latex mattress is made with latex foam derived from either Talalay or Dunlop latex. Latex is bouncy, responsive, and cooling. It’s also really durable. A lot of latex mattresses combine the latex with other materials, like coils or polyurethane foam.
Fiberglass Alternatives
A few alternatives to fiberglass that we see in mattresses include wool, cotton, polyester and rayon. These are all flame retardant materials like fiberglass however offer more comfort, are better for the environment and our health. Brands like Saatva use a plant-based thistle as an alternate to fiberglass and other brands like Big Fig use a blend of cotton and other organic materials in its original mattress.
Sleeping Position
Here’s a brief overview of what mattresses might be good for the different sleeping positions.
- Back sleepers: These sleepers don’t tend to need too much from their bed and mainly need their bed to be comfortable and supportive. They usually do best on hybrid or innerspring mattresses.
- Side sleepers: Side sleepers tend to need a softer mattress in order to get nice cushioning and pressure relief for their shoulders and hips. They typically do well on foam mattresses, although they can also find a match in many hybrid beds.
- Stomach sleepers: Stomach sleepers need a firmer and more supportive mattress in order to keep their hips lifted and in line with their shoulders — ensuring healthy sleep posture. We usually steer stomach sleepers toward innerspring mattresses, although there are some hybrids that can work well for them.
- Combination sleepers: This refers to sleepers who switch positions throughout the night. They need a responsive bed that allows them to easily move around and change sleeping positions. They typically do well on latex mattresses, hybrid mattresses, and innerspring mattresses.
Body Types
At Sleepopolis, we categorize lightweight sleepers as weighing less than 130 pounds, average-weight sleepers as weighing between 130 and 250 pounds, and heavy sleepers as weighing more than 250 pounds.
We typically recommend heavier sleepers look for an innerspring mattress or on our roundup of the best mattresses for heavy people. This list consists of beds built especially for larger folks. When looking for fiberglass-free mattresses for heavy sleepers, prioritize support and durability with high-density foam or sturdy innerspring coils. Choose options that offer good comfort and pressure relief, ideally medium to firm, to ensure proper spinal alignment. Lastly, check for safe materials and certifications like CertiPUR-US to confirm the absence of fiberglass.
Firmness
Your body type and preferred sleeping position are crucial considerations when selecting a mattress, and its imperative to keep both in mind when deciding the perfect firmness to you.
The mattress industry tends to measure firmness on a scale of one to 10, with one being the softest and 10 being the firmest. We categorize a mattress with a 6.5 out of 10 score as medium-firm, meaning it possesses the most even balance of comfort and support.
Softer mattresses (3 to 6 out of 10 on our scale) are typically best for side sleepers, those with joint pain, and lightweight folks. Medium-firm beds (6.5 out of 10) typically benefit back sleepers, average-weight sleepers, and combination sleepers best.
Firmer beds (7 out of 10 or more) do best at supporting most stomach sleepers and heavier folks to press through more of the mattress materials. For an in-depth walkthrough, see our official Mattress Firmness Guide.
Durability of Fiberglass-Free Mattresses
Fiberglass-free mattresses tend to be more durable than those containing fiberglass, as they often utilize higher-quality materials. Experts suggest that mattresses made from natural latex or high-density memory foam can last 10 to 15 years, while lower-quality options may only last 5 to 8 years. In contrast, mattresses with fiberglass may degrade more quickly, leading to potential comfort issues over time. Materials like natural latex and high-density polyfoam are known for their longevity, whereas traditional, cheaper memory foam may be less durable if of lower density. Overall, investing in a quality fiberglass-free mattress can enhance both durability and long-term comfort.
Cooling
A mattress with solid temperature-regulating features will improve your sleep tremendously by helping you keep cool through the night. When testing each mattress in our studio, we use a thermal temperature control gun to help us understand where each mattress holds the most amount of heat.
Our testers lay for several minutes on the mattress and then measure how long it takes the mattress to go back to its original temperature. We consider an 8 degree change or under to be good cooling, and a change of 5 degrees and under to be great cooling.
Motion Isolation
If you’re looking for a fiberglass free mattress but also want this bed to work for you and your partner, and/or kids, or pets, motion isolation is a crucial factor you should think about. Motion Isolation refers to the amount of movement that is felt across the mattress when the person laying next to you changes position or gets into and out of bed.
We test the motion isolation for each mattress in a couple different ways. One of our go-to tests is the ball drop, where we drop a steel ball from different heights and use a seismograph to measure the movement felt across the bed. The bigger the ripple, the worse the motion isolation. In general, we find that foam and hybrid mattresses have the best motion isolation because of their medium-firm nature so keep that in mind when looking at fiberglass free mattresses.
Hear from the Experts:
Would You Recommend That Sleepers Buy a Fiberglass-Free Mattress?
“Yes, it’s a good choice to pick a fiberglass-free mattress to avoid the health problems associated with having exposure to fiberglass. Choose mattresses that explicitly say they are fiberglass-free, or look for materials like natural latex or organic cotton, both known for offering exceptional safety and comfort when it comes to mattresses.”
Edge Support
Edge support in a mattress refers to how well the edges resist compression when weight is applied, allowing sleepers to use the entire surface without feeling like they’re rolling off. It’s especially important for heavier sleepers, seniors and those who tend to sit on the edge, as it helps maintain stability and prevents sagging.
Fiberglass-free mattresses often perform well in edge support, particularly those with high-density foam or sturdy innerspring coils. For optimal edge support, natural latex or hybrid beds are top contenders, as they provide excellent resilience and firmness at the edges. We test edge support by sitting on the edge of the bed and using a yard stick to measure how much sink is experienced by our testers.
Pain Relief
When seeking pain relief in a mattress, look for medium-firm options that offers balanced support for the spine, helping alleviate back pain. Memory foam or latex materials can contour to the body, providing relief from shoulder pain by reducing pressure points. For neck pain, consider a mattress that supports proper alignment and offers cushioning around the head and shoulders.
Adjustable bases are also great options for anyone struggling with chronic pain and can further enhance pressure relief by allowing you to elevate the head or feet, which can help reduce discomfort in the neck and back. Always test a mattress for comfort and support, ensuring it meets your specific pain relief needs.
Mattress Company Policies
Shipping
Cost and shipping methods are concerns for every shopper. However, when looking for a mattress without fiberglass, a main concern you have may be avoiding overly expensive beds and online shopping. We can assure you that there are mattresses that can be purchased online without breaking the bank that do not have fiberglass, and we made sure to look into the shipping safety and costs of the mattresses on this list .
If you are shopping internationally you may want to look into our picks for the best Canadian mattresses to learn more about how they are made and shipped.
Sleep Trials & Returns
When buying your new fiberglass free mattress, make sure to look out for the brands warranties, return policies and sleep trials. Typically, we recommend testing a mattress for 30 days to see how our body adjusts to it. Most brands have a 60-90 day sleep trial period which allows you to determine if you want to keep it with no financial burden if you choose to return it.
Mattress Warranties
The warranty of your mattress is how long a mattress company is willing to ensure the durability of your mattress and generally means that if something happens to the mattress within that time frame, that they will replace it free of charge. Many companies offer a 10-year warranty, while others offer life-time warranties.
Keep in mind, typically the higher your price-point of mattress, the better the policies. All the brands we have chosen offer great company policies and we feel very comfortable recommending them to you.
FAQs
What is fiberglass?
Fiberglass is a composite material made of glass and reinforced plastic. It’s used in a variety of products and places, from wall insulation to mattresses. It’s known for being very malleable, durable, and inexpensive, which is why manufacturers like to use it.
Do all mattresses have fiberglass?
No. Not all mattresses contain fiberglass. However, many do, as it’s an effective flame retardant. Fiberglass is less expensive than a lot of other options out there, which is why many companies use it.
Is fiberglass dangerous?
Fiberglass is really only dangerous if you’re directly exposed to it. If it remains beneath your mattress cover (or perhaps under a mattress protector as well), you shouldn’t have a problem with it. The issues arise when a poorly made or damaged mattress releases the glass fibers and humans come into contact with them. If this happens, the fiberglass can irritate or cause damage to people’s eyes, lungs, upper respiratory tract, or skin.
Is fiberglass in mattresses illegal?
No. It meets the federal safety standards for open-flame fire resistance in mattresses. However, it’s supposed to be completely contained and covered when it is used in beds.
Should I only purchase mattresses without fiberglass?
That’s up to you. Fiberglass can be safe to have in a mattress if it’s properly concealed, but some consumers prefer to forgo any risk of being exposed to it and buy a mattress without fiberglass instead.
What do I do if my mattress has fiberglass?
It’s important to never remove your mattress cover if the bed contains fiberglass. We also recommend adding a mattress protector to your bed for extra protection. If your bed is showing wear and tear, it’s a good idea to replace it. If its exterior is still in good shape, a good rule of thumb is to replace a mattress after five to 10 years.
Do most memory foam mattresses have fiberglass?
Most budget friendly memory foam mattresses contain fiberglass however fiberglass isn’t limited to just memory foam mattresses. The more money you spend on your mattress the less likely it has traces of fiberglass.
How We Chose These Mattresses
Our team of Certified Sleep Science Coaches has reviewed more than 300 products in Sleepopolis’ mattress lab, running each one through tests such as pressure-mapping and measuring motion transfer with a seismometer. From there, we give every bed an overall score based on materials, comfort, support, cooling, and edge support. We also factor in brand performance with categories such as value and warranty.
For the mattresses on this page, we made sure they don’t use fiberglass in any form (or under any name) in their materials. Instead, they commit to being fiberglass-free and use other flame-retardant alternatives, like cotton, wool, rayon, latex, and proprietary blends. Click here to learn more about our methodology.
