Best Mattresses without Fiberglass
Written by Livvi DiCicco, Certified Sleep Science Coach
Just the word “fiberglass” strikes fear into the heart of many mattress shoppers. This material, though prized for its affordability, insulating properties, and fireproofing, is associated with a range of adverse health effects.
Most manufacturers have moved away from using it in their mattresses, opting for natural or synthetic alternatives that won’t cause problems for the lungs or skin. However, the occasional cheap mattress could cut corners.
The good news is that we’ve reviewed hundreds of mattresses and have plenty to recommend that are certified fiberglass-free. Many proudly advertise it on the product’s page, and for some, we made sure to connect with customer service representatives and get the thumbs-up. Below, our nerds have picked out nine of the best mattresses without fiberglass that’ll get you on your way to safe, comfortable sleep.
Bottom Line: What is the Best Mattress Without Fiberglass?

Helix Midnight Luxe – Nerd’s Pick
Helix Midnight Luxe Mattress
Product Details
Our Recommendation
The Helix Midnight Luxe is one of the brand’s most popular models: a luxurious hybrid with a thick pillow top and individually wrapped coil unit. And more good news: all Helix mattresses are made without fiberglass, including the Midnight Luxe!
This mattress boasts a comfy medium feel that should accommodate most side and back sleepers, relieve pressure, and provide spine-aligning support. On top of that, this mattress earned several high scores for its rock-solid edge support, cooling performance, and responsiveness.
It’s a great place to start if you’re after a well-rounded bed without an ounce of fiberglass. If it couldn’t get any better, you get a generous 365-night sleep trial and lifetime warranty with your new Helix Midnight Luxe.
What our testers say: “I think side sleepers will also fare well on the Helix Midnight Luxe mattress. The gentle cushioning from its top layer should provide some much-needed pressure relief in pain-prone areas, such as the shoulders and hips.” – Kenny Timper, Staff Writer & Mattress Tester
Who Might Like the Helix Midnight Luxe
- Side and back sleepers – Our test thought this mattress offered a good mix of softness and support, skewing a little softer than true medium-firm. This will work best for back and side sleepers who like contouring.
- Those who frequently sit on the edge of their mattress – Whether you sit or lie down at the perimeter of your mattress, you shouldn’t have any trouble feeling stable, thanks to this bed’s sturdy edge support.
Who Might Not Like the Helix Midnight Luxe
- Stomach sleepers over 230 pounds – This bed is a bit too soft to keep these sleepers’ hips lifted and aligned with the rest of their bodies.
- Budget shoppers – As a luxury mattress, the Midnight Luxe costs nearly $2,000 for a queen, and that’s after you factor in discounts and sales.
What users say:
According to Helix’s website, the Midnight Luxe scores 4.5 out of 5 stars from thousands of customer reviews. Negative comments come mostly from shoppers who found the mattress too firm and therefore uncomfortable for their personal preference. But the majority of positive reviews praise the bed’s pain relief, easy set-up, and overall comfort.

Nectar – Best Affordable Mattress Without Fiberglass
Nectar Classic Memory Foam Mattress
Product Details
Our Recommendation
If you want an affordable, top-quality mattress sans fiberglass, you can’t go wrong with the Nectar. This all-foam mattress is popular for a reason. It’s a high performer in support, durability, and, most importantly, available for under $1,000 for a queen-size.
We love this medium-firm mattress for back sleepers, couples, and those who run hot. Unlike a typical foam bed, the Nectar boasts a surprisingly cool cover and a more responsive, “on top” feel. You won’t sink deeply into this bed as you might expect, but the comfort foams do provide good contouring and absorb any movements from a restless partner or pet.
What our testers say: “The Nectar Classic is a solid option for back sleepers because it is firm enough to keep their hips aligned with the rest of their bodies and prevent them from sinking too far into its foams. During my hands-on assessment of this mattress, I found that its balance of medium-firm support and gentle contouring helped relieve pressure in my lower lumbar region.” – Kenny Timper, Staff Writer & Mattress Tester
Who Might Like the Nectar
- Hot sleepers – We found this mattress felt cool to the touch on the surface, and it didn’t noticeably heat up when we lay on it throughout testing. Foam usually traps heat, so we consider this quite impressive.
- Couples – If your partner tosses and turns, you shouldn’t feel it on the Nectar. Light sleepers can therefore rest undisturbed throughout the night.
Who Might Not Like the Nectar
- Side sleepers with sensitive joints – Because the Nectar doesn’t have as much sinkage as a super-soft foam bed, those who sleep on their side won’t get the pressure relief they need around the hips or shoulders, which can worsen pain.
- Those who want a bouncy bed – Though the Nectar was more responsive than expected, it’s not a springy mattress. It still feels like a block of foam, not a hybrid with coils.
What users say:
With thousands of reviews on Nectar’s website, the Nectar mattress has an average of 4.7 out of 5 stars. The majority of negative reviews found the bed too firm, too soft, or thought it started to sink too quickly. But positive reviews praise its comfort and cushioning ability.

Leesa Original – Best Memory Foam Mattress Without Fiberglass
Leesa Original
Product Details
Our Recommendation
Memory foam is a popular choice for affordable yet quality mattresses, but when it comes to cheaper options, you have to be wary of the possibility of fiberglass in their construction. The Leesa Original is a completely fiberglass-free memory foam bed and one of the few that scored 4s or higher in all our testing categories.
This bed earned perfect ratings for ease of movement and cooling, two areas where foam beds tend to lag behind. It also has a firmer, more supportive feel that’s balanced out by the bed’s above-average pressure relief. If you’re unsure where to start with a fiberglass-free foam bed, this bed checks all the boxes.
What our testers say: “Back sleepers need a sleep surface that balances both softness and support, which the Leesa Original excels at. While the initial feel of this mattress is quite firm, there’s enough plushness from the top layers to contour to the lower back. Not one of our testers complained about any pressure across their spine.” – Livvi DiCicco, Staff Writer & Mattress Tester
Who Might Like the Leesa Original
- Sleepers who run hot but want a foam bed – Though it’s made entirely of foam, which has a reputation for trapping heat, this bed has plenty of cooling features. The Leesa mattress felt super cool throughout our tests, never raising concerns that we might overheat on it.
- Combination sleepers who like firmness – It’s super easy to move around on the Leesa Original as you won’t sink in or feel “stuck.” Our testers also found the bed’s firm but pressure-relieving feel suited to every sleeping position.
Who Might Not Like the Leesa Original
- Especially light sleepers – The Leesa earned its lowest rating for motion isolation at 4 out of 5. It should satisfy most couples, but sleepers prone to waking may want something that completely absorbs any and all motion.
- Folks who want to sink deeply into their bed – You’ll feel more “on top” of the Leesa than hugged by it. You should still get plenty of pressure relief, but it may not be the typical preference of memory foam fans.
What users say:
This mattress has thousands of reviews on Leesa’s site, helping it to earn a rating of 4.5 out of 5 stars. Negative reviews focus on the bed’s firmness and feel, which is largely subjective, with some mentioning the bed’s off-gassing smell. Many customers enjoy the extra firmness of this bed for added support to address back pain.

DreamCloud – Best Mattress Without Fiberglass for Back Pain
DreamCloud Original Mattress
Product Details
Our Recommendation
Financing Options
Financing options are available for this mattress.
Folks with back pain looking for a mattress without fiberglass have double the trouble in their search. However, it ends here with the DreamCloud mattress. This fiberglass-free hybrid is slightly firmer than the average bed, offering spine-aligning support that reduces the risk of back pain. Moreover, its thick pillow top ensures the lumbar spine gets all the contouring it needs.
Aside from its pain-relief properties, the DreamCloud’s support should extend to the edges, and its coil unit provides plenty of bounce. Best of all, this bed has a luxury feel without the high price: You can purchase a queen-size DreamCloud for about $699, and it comes with a 365-night trial and lifetime warranty.
What our testers say: “The DreamCloud has a true hybrid feel. When you first lie down, you feel cushioned by the soft memory foam top layers. The further you sink into the mattress, the more you notice the support of the coil layer. We feel more ‘on top’ of this mattress than hugged by it.” – Livvi DiCicco, Staff Writer & Mattress Tester
Who Might Like the DreamCloud
- Budget shoppers – It’s rare to find a high-quality hybrid for under $1,000, but the DreamCloud starts out at just $349 for a twin size.
- Combination sleepers – Moving around on the DreamCloud is as easy as breathing, so switching between your preferred positions will feel seamless.
Who Might Not Like the DreamCloud
- Traditional foam fans – Though they contain foam in their construction, we wouldn’t say the DreamCloud has a slow-moving, deep-contouring feel. I’d describe it as springy and lifted.
- Stomach sleepers over 230 pounds – Despite its firmness, our heavyweight testers noticed a bit more sinkage than they’d like in this position.
What users say:
On DreamCloud’s site, this mattress has a 4.6-star rating out of thousands of reviews. Most negative reviews discuss that the firmness is either too firm or too soft for the customer’s taste. The majority of customers say they’ve been sleeping much better on their DreamCloud mattress and praise its comfort.

Brooklyn Bedding Signature Hybrid – Best Hybrid Mattress Without Fiberglass
Brooklyn Bedding Signature Hybrid
Product Details
Our Recommendation
The Brooklyn Bedding Signature Hybrid is precisely that: signature. It checks all the boxes you could want in a hybrid mattress, and on top of that, it’s completely fiberglass-free. We awarded it high marks for its pressure relief, motion isolation, and ease of movement. It’s a versatile pick that should suit many sleeper types, especially those seeking a medium-firm feel with both softness and support.
Available in three different firmness options, the Signature Hybrid can further cater to a variety of tastes. We found the Medium model was a great match for couples, back sleepers, and side sleepers of all sizes. This mattress-in-a-box is also fairly priced at under $2,000 for a queen size, and Brooklyn Bedding gives you a full year to decide if it’s right for you.
What our testers say: “Thanks to its high-quality materials and robust eight-inch coil system, the new Brooklyn Bedding Signature Hybrid is built for long-term durability. Its sturdy support core helps maintain the mattress’s structure over time, adds extra stability, and helps guard against early sagging. With proper care and occasional rotation, sleepers can reasonably expect this mattress to perform well for 10 years or more.” – Kenny Timper, Staff Writer
Who Might Like the Signature Hybrid
- Light sleepers who share the bed – Our tester thought that though this mattress had a good amount of bounce, it still absorbed movement from the other side of the bed. Couples should be able to sleep soundly beside one another.
- Side and back sleepers with back pain – The Signature Hybrid features zoned support in its coil unit to ensure you get the lift you need in the center of the mattress. Its pillow top also melted away pressure around our testers’ hips, shoulders, and lower back.
Who Might Not Like the Signature Hybrid
- Especially hot sleepers – This bed includes components like gel memory foam and a breathable cover to wick away heat, but we didn’t find it felt cool. While most sleepers shouldn’t overheat, those who want a truly chilly mattress should look elsewhere.
- Folks who need a sturdy perimeter – We thought the edge support for this mattress was just alright. You shouldn’t feel unstable when you lie along the perimeter, but sitting down at the edge caused quite a lot of sinkage.
What users say:
On the Brooklyn Bedding website, this mattress scored 4.7 out of 5 stars based on 10,198 reviews. The reviews speak highly of the comfort levels, describing it as a great mix of softness and support. There were complaints about the customer experience and support, as no one has gotten back to them in a while, and they still haven’t received their mattress.

Helix Dawn – Best Queen Mattress Without Fiberglass
Helix Dawn Mattress
Product Details
Our Recommendation
Queen-size mattresses are the most popular picks for single sleepers and couples alike, providing you plenty of space to snuggle up or spread out. Helix doesn’t miss with its hybrid mattresses, and if you’re after a fiberglass-free option that brings the support, you’ll love the Helix Dawn. It was originally designed for stomach sleepers, so it brings lift with a capital L without the unyielding rigidity associated with extra-firm beds.
Speaking of rigidity, you’ll be pleased with the Dawn’s rock-solid edge support. The bed’s firmness also means you’re buoyed right on the surface, with our testers recommending it for combination sleepers who rest on their back or stomach. You can also snag a queen for just about $1,000. And if you’re not quite sure you want to take the plunge, take full advantage of Helix’s 365-night trial.
What our testers say: “When you lie down, you’ll experience a firm, supportive feel, but lightweight sleepers and even some average-weight sleepers may find it too firm. Its firmness level and overall feel is best for strict stomach and back sleepers who are average-weight or heavyweight and prefer a firm, supportive mattress.” —Rachael, Editor & Mattress Tester
Who Might Like the Helix Dawn
- Back and stomach sleepers – The Dawn’s firmer feel is best suited to these sleepers, especially if their current bed isn’t giving them enough lift.
- Restless sleepers – Our testers were able to roll around on this mattress without feeling impeded, so sleepers that toss and turn won’t have to put any effort into getting comfortable.
Who Might Not Like the Helix Dawn
- Couples – The motion isolation on the Helix Dawn was a bit disappointing. Our testers could feel one another clearly, which spells trouble for light sleepers who share the bed.
- Sleepers with joint pain – A softer mattress that provides better pressure relief is a better option for these folks.
What users say:
The Helix Dawn has an average of 4.6 out of 5 stars on the Helix website. Negative reviews say that the mattress seems to get softer over time, but the majority of positive reviews claim the bed is comfortable and has helped with aches and pains.

Brooklyn Bedding CopperFlex Foam Mattress – Best Firm Mattress Without Fiberglass
Brooklyn Bedding CopperFlex Memory Foam
Product Details
Our Recommendation
As a firm mattress lover myself, you can’t go wrong with the CopperFlex Memory Foam mattress. This is a rare ultra-firm, all-foam bed that’s reasonably priced for the level of support you’ll get. And despite that low price, there’s no fiberglass in its construction. Brooklyn Bedding states that any fireproofing material is made with a silica, rayon, and polyester blend.
We rated this mattress at a 7.5 out of 10 on our firmness scale, a whole point above traditional medium-firm. Thanks to this firmness, the CopperFlex is also surprisingly responsive for a foam bed, and its edge support doesn’t quit either. The deal is only sweetened when you consider the price: typically around $600 for a queen.
What our testers say: “This is a good pick if you like to feel ‘on top’ of your mattress. It’s super firm and especially bouncy for an all-foam bed, but it still isolates motion, which is rare. If that’s your preferred feel, you’ll love this bed’s low price tag, too.”– Livvi DiCicco, Expert Mattress Tester
Who Might Like the CopperFlex
- Stomach and back sleepers – The CopperFlex’s high-density foams provide a firm, supportive surface for stomach and back sleepers.
- Couples who want a good mattress for sex – The CopperFlex’s strong edge support and ease of movement mark should make intimacy more fun and less cumbersome. You’ll have plenty of space to work with, and you won’t feel impeded by the mattress as you switch positions.
Who Might Not Like the CopperFlex
- Side sleepers – Since there’s not much sinkage from this mattress, our testers noted pressure buildup in their hips and shoulders when they rested on their side.
- Folks who want a bed that feels super cool – The CopperFlex gets its name from its copper-infused foams, a miner that purportedly helps with wicking away heat. However, we found the mattress felt temperature-neutral at best, far from icy cold, as it was advertised.
What users say:
With hundreds of reviews, the Brooklyn Bedding CopperFlex earns 4.5 out of 5 stars from customers. Most customers praise the mattress’s value for its construction quality and performance. However, a number claim the bed isn’t as cool-feeling as advertised.
Our Brooklyn Bedding CopperFlex review is still in the works.
Leesa Sapira Chill Hybrid – Best Cooling Mattress Without Fiberglass
Leesa Sapira Chill Hybrid
Product Details
Our Recommendation
I’ve been blessed with chronic night sweats, and I know firsthand how a cooling mattress goes a long way. If you’re after a bed that feels both cool and comfortably cushioning, look no further than the Leesa Sapira Chill Hybrid. This mattress lives up to its name, earning high marks in our cooling evaluation for how cold it remained throughout testing. Best of all, Leesa says their rayon fiber barrier is made from 100-percent regenerated cellulose, not fiberglass.
Aside from cooling, the Sapira Chill Hybrid is a good option for folks who need extra contouring and cradling, as even the Medium-Firm model felt somewhat softer than expected. Our testers also enjoyed this mattress’s relatively strong edge support and responsive feel, despite this softness up top.
What our testers say: “I was very impressed by the cooling abilities of the Leesa Sapira Chill. The cover has a cool-to-the-touch feel that stayed the whole time I was lying on it. I didn’t notice the bed heating up, and I honestly think its name is pretty accurate: chill. I would for sure recommend this bed to hot sleepers. The gel-infused foam quilted into the pillow top was noticeably cool.”– Riley Otis, Expert Mattress Tester
Who Might Like the Leesa Sapira Chill
- Side and back sleepers who need extra pressure relief – We consider the Leesa Sapira Chill Hybrid one of the best mattresses for side sleepers because of how well it contours the hips and shoulders. Back sleepers who like a bit of softness should also appreciate the sinkage they’ll receive in this position, which will keep tension off the lower back.
- Seniors – This mattress is light on the joints while remaining fairly responsive, a good combination for older adults and those with mobility concerns. Its strong perimeter can also help with transferring in and out of bed.
Who Might Not Like the Leesa Sapira Chill
- Stomach sleepers – Even the firmest model of the Sapira Chill Hybrid may not be enough to support stomach sleepers, especially if they weigh more than 130 pounds.
- Extra-light sleepers who share the bed – Our testers dubbed this bed’s motion absorption as simply “average.” If you’re like me and wake at the slightest twitch, I’d look elsewhere.
What users say:
According to Leesa’s website, the Leesa Sapira Chill Hybrid has earned 4.3 out of 5 stars from more than 250 customer reviews. Many buyers praise the mattress’s support and pressure relief, with some even saying it’s helped alleviate their back or hip pain. However, a few customers complain about delivery issues or that the mattress is firmer or softer than advertised.
Our Leesa Sapira Chill Hybrid mattress review is still in the works.
WinkBed – Best Luxury Mattress Without Fiberglass
WinkBed Mattress
Product Details
Our Recommendation
Financing Options
Financing options are available for this mattress.
Unfortunately, many so-called luxury mattress brands still cut corners with fiberglass. That’s not the case with the WinkBed. This hybrid boasts a classic innerspring feel plus a thick, dense, and cushy pillow top that’ll make it seem like you’re at a five-star hotel. Best of all, there’s not a lick of fiberglass to be found in it.
The WinkBed comes in four different firmness options, and the aptly named Luxury Firm offers support with a touch of cushioning up top. It should also be a popular choice for couples, as we also found this mattress absorbs motion and remains firm along the edges. This means you and your partner can spread out and switch positions without disturbing one another.
What our testers say: “This luxury bed’s hybrid construction offers a balance of support and softness, though we’d say you mostly feel the former. The softer pillow top does provide some cushioning at the surface, but you quickly sink through it and feel the lift from the sturdy coil base. This is what we mean when we say you’ll feel more “on top” of this mattress, rather than deeply hugged by it like you would a traditional all-foam mattress.” – Loren Bullock, Expert Mattress Tester
Who Might Like the WinkBed
- Folks with back pain – The Luxury Firm model of the WinkBed feels medium-firm and provides an ideal balance of softness and support, which should keep the spine aligned in most positions and stave off back pain.
- Those who gravitate toward the edge of their bed – The edges of the WinkBed shouldn’t buckle or collapse when you sit or lie down along the far reaches of the mattress.
Who Might Not Like the WinkBed
- Sleepers who want a springy mattress – Despite its coil construction, the WinkBed isn’t very bouncy, which could make it difficult for some sleepers to move around.
- Shoppers looking for luxury on a budget – The WinkBed mattress is priced fairly run-of-the-mill for a luxury mattress, but this may not accommodate all budgets. You can expect to pay about $1,800 for the standard models and a couple hundred bucks more for the Plus.
What users say:
On the WinkBeds site, the WinkBed earns a 4.8 out of 5 stars. Most negative reviews focus on problems with delivery and removal. Overall, people seem satisfied and find the bed supportive and sturdy.

What is Fiberglass?
Fiberglass (also called fibrous glass, glass wool, glass fibers, etc.) is precisely what it sounds like: synthetic fibers made from small glass particles, produced by melting minerals at extremely high temperatures. The result is a shiny and extremely fine material that’s most commonly used for fiberproofing and insulation in textiles, homes, and other industrial pursuits.
Why Is Fiberglass Put in Mattresses?
In the United States, mattresses must comply with flammability standards, helping to reduce the risk of injury or death from mattress fires. As fiberglass is a cheap and effective fire barrier, it was once a popular choice for fireproofing beds. However, more recent realization of the negative health effects of fiberglass has shifted manufacturing priorities. Contact with fiberglass has been associated with skin and lung irritation, and prolonged exposure can lead to more significant health concerns, such as asthma or recurrent dermatitis.
What to Look For in the Best Beds Without Fiberglass
Obviously, the first order of business in choosing the best mattress without fiberglass is ensuring it doesn’t have it listed in its construction. From there, we take a look at things like its budget, firmness and feel, and other performance areas that appeal to certain sleeper types.
Construction
Fiberglass is typically found in what’s called the firesock for the mattress. It’s a layer that encases the mattress to act as a flame barrier. The foams and fabrics typically found in mattresses are quite flammable, so this is added to ensure that if a fire were to start, your mattress wouldn’t turn into a flaming rectangle.
I’ll also note that you might also see fiberglass labeled as “glass fibers,” “glass wool,” “glass filament,” or other not-quite-synonyms. If something sounds fishy, there’s a good chance it’s fiberglass. Most fiberglass alternatives are some form of wool (that’s organic wool), rayon, or even polyester.
The majority of manufacturers are happy to disclose that their mattresses are fiberglass-free, so you shouldn’t have to go searching for whether the bed you want contains this material. A good place to find this information is in the FAQs section of a brand’s site, or by contacting a representative. For many of these recommendations, we reached out to customer service to confirm that these beds are completely without fiberglass.
Type of Mattress
You may be worried that one type of mattress is more likely to contain fiberglass than another. While fiberglass can be in any mattress, it’s more often found in cheaper options, which means it’s commonly associated with foam beds. But both innerspring mattresses and hybrid mattresses, though they cost more, could use fiberglass in their fire barrier.
The one type of mattress that you’re unlikely to find fiberglass are those made with latex foam. Most of these beds are described as all-natural with no synthetic components, an umbrella under which fiberglass would fall. Wool is the preferred alternative for fireproofing, and it’s also hypoallergenic. Of course, latex mattresses are the most expensive kind out there, so some may not be able to justify the price for total peace of mind.
Certifications
Though there’s no certification that denotes a mattress as fiberglass-free, they’re a good sign that a manufacturer has your safety in mind. Here are some popular certifications you may see mattresses sport, and what they mean:
- CertiPUR-US Certified Foams: The foams inside are treated without any harmful chemicals and also meet the standard for VOCs (emissions).
- OEKO-TEX Standard 100: The textiles in this mattress have all been tested to ensure they don’t contain a list of harmful chemicals.
- GOTS and GOLS (Global Organic Textile and Global Organic Latex Standard): This certifies that the textiles (such as organic cotton) and latex in the mattress are at least 95-percent organic, and the manufacturing process is up to standards.
- GREENGUARD Gold Certified: The finished mattress meets the standard for low emissions.
For more information, check out our mattress certification guide.
Budget
I’d stay away from most mattresses that are under $500 for a queen-size. It’s a sign that they’re cheaply made, and cutting corners with fiberglass is a popular option to reduce costs.
But better news: the affordable mattresses on this list have all been vetted as fiberglass-free — so it is possible. I just wouldn’t play roulette, especially if you’re sorting by price on Amazon’s homepage.
Other Considerations for Fiberglass-Free Mattresses
Aside from the areas above, which directly correlate to whether a mattress contains fiberglass, there are other factors that could determine which mattress is best for you. These will have more to do with your personal preferences and sleeping styles.
Firmness
Firmness is another way of describing how soft or hard a mattress feels. We rate firmness on a scale of 1 to 10, with 1 being soft as a cloud, and 10 like lying on the floor. You’ll rarely find mattresses on either end of the spectrum. Most fall around 6.5/10, or medium-firm, the perfect blend of softness and support.
Most sleepers should be comfortable on a medium-firm mattress because of its balanced feel. However, some sleeping positions and body types may fare better on a bed that’s softer or firmer.
Sleeping Position & Body Type
Here’s what we recommend for each sleeping position:
- Back sleepers: Medium to medium-firm mattresses work well for these sleepers. They should help coax the spine into proper alignment and relieve pressure at the lower back.
- Side sleepers: Side sleepers fare better on medium to soft mattresses, as these allow for the necessary sinkage around the hips and shoulders.
- Stomach sleepers: Firmer mattresses are best for stomach sleepers. It’s important to keep your hips elevated so you don’t develop back pain.
- Combination sleepers: If you switch between multiple positions, a medium-firm mattress is a good middle-ground to accommodate different sleep styles.
You’ll also want to temper these recommendations with your weight. We’ve found that sleepers with a larger frame may sink further into the mattress than expected, and extra firmness can give them the added support they need. On the other hand, those who weigh less than 130 pounds may not sink in far enough. In this instance, a softer bed can ensure they get the pressure relief they need.
Other Performance Categories
The following categories are important to consider if you share the bed, sleep hot, or have mobility concerns.
Edge Support
A mattress with strong edge support holds its shape when you sit or lie along the perimeter. This can make it easier to transfer in and out of bed, a plus for seniors or those with limited mobility. We also claim robust edges are a sign that the mattress won’t sag with repeated use, so you can count it as a durability marker.
Motion Transfer
If you sleep beside a partner who tosses or turns, you may have woken up from their movements. Chances are, your mattress has poor motion isolation. A bed with thick, dense layers (like memory foam) can absorb movement before it travels across the mattress surface. Couples and light sleepers should choose a mattress that scores high in this area.
Ease of Movement
Sometimes, when you move around on top of a mattress, you might encounter some pushback that makes you feel “stuck” as you sink into it. If you hate this feeling, you’ll want a mattress with better ease of movement, also called responsiveness. A responsive mattress springs back into shape when you bear down on it, so it doesn’t hold onto you as you switch positions. Combination sleepers and those with limited mobility will benefit from a high responsiveness rating.
Cooling
Many mattresses contain cooling features like specialized covers, breathable foams, and pocketed coils to wick away excess heat and keep air flowing. But it’s not enough to have these features, they have to pull their weight. So, we rate every bed’s cooling capability out of 5. I’d recommend that hot sleepers stick to beds that score at least a 4 in this category, with those who want an icy, cool-to-the-touch feel gravitating toward 4.5 and 5 out of 5 ratings.

Final Thoughts
Fiberglass is cheap but linked to adverse health effects, so many manufacturers have strayed away from using it in their products. However, the occasional budget mattress may be hiding fiberglass in its construction as a fire barrier. To help shoppers find top-quality mattresses without fiberglass, we ensured our picks are made with certified safe materials, but also top performers in areas that should appeal to the majority of sleepers.
FAQs
What mattresses should I stay away from?
Mattresses with fiberglass are often on the cheaper side. Many Amazon mattresses contain fiberglass, which is unsurprising when you consider that many cost less than $200. At some point, you have to realize when affordability crosses the line into cutting corners.
And, of course, aside from mattresses with fiberglass, choose a bed that you know is going to work best for your budget and preferences. There are many affordable mattresses on this list that don’t contain fiberglass, as well as luxury ones. You can also find a range of firmnesses and feels to accommodate your sleeping position, body type, and any other concerns that impact your comfort.
What is the least toxic mattress brand?
There’s no one “least toxic” brand, but there are a few all-natural mattress brands that could appeal to eco-conscious shoppers. Birch and Avocado mattresses are all-natural and made without synthetic materials, including fiberglass. Latex beds, like those from these brands, are often great picks for an organic and fiberglass-free mattress.
Do Ashley mattresses have fiberglass?
Some Ashley mattresses used to have fiberglass in them, but as of 2024, all mattresses should not have fiberglass in their construction. It has been replaced with a natural, safer flame retardant. If you have an older mattress in your home from before that date, it may contain fiberglass.
What brands of mattresses have fiberglass in them?
Brands often will advertise that their mattresses are fiberglass-free as a selling point for consumers. However, those that do will not be so forthcoming, listing a “flame-resistant barrier” and other vague descriptions in the bed’s construction.
Two mattresses that are suspected to contain fiberglass are the Sleep Number ComfortMode and the Canadian versions of the Puffy and Puffy Royal mattresses. A number of generic-brand budget mattresses on Amazon also seem to have fiberglass components in their construction, so tread carefully. Older versions of mattresses currently listed as fiberglass-free may contain fiberglass — something to keep in mind when buying used or accepting one secondhand.
What is the healthiest type of mattress to sleep on?
We recommend latex mattresses for those concerned about a natural, safe mattress. Latex is an organic material derived from the rubber tree. These beds typically contain other organic components, like wool and cotton, which replace fiberglass as a fire retardant. Some examples of our favorite organic mattresses without fiberglass are the Avocado Green mattress and the Birch mattress.
Do Serta mattresses have fiberglass?
Some have reported that older Serta models, like the Serta iComfort, were made with fiberglass. However, it would appear that the mattresses offered by Serta today do not list fiberglass in their construction.
Is it safe to sleep on a mattress with fiberglass?
The good news is that even if your mattress contains fiberglass, it shouldn’t be in a place you can touch or inhale — unless you cut into or remove the mattress cover. Most manufacturers put fiberglass in the outer cover of the mattress to prevent fires, so if you don’t puncture, cut, or disturb this layer, you shouldn’t be exposed to fiberglass. For peace of mind, I’d recommend a mattress without fiberglass, as accidents happen.
Studies have shown that fiberglass can cause more harm than good. Inhalation of fiberglass fibers has been associated with respiratory issues — with the United States’ National Toxicology Program reporting inhalation of fiberglass as “reasonably anticipated to be a human carcinogen,” though I’ll note it does not officially classify it as one. Coming into contact with fiberglass has also been associated with dermatitis (skin irritation) and other concerns for the skin.
