We’ve recently updated this list to include more fiberglass-free mattresses and added extra information from our testers. If a bed’s on this list, you can be confident we’ve not only personally tested it, but we’ve also contacted the business and searched for language on their website to find out the exact materials in their beds.

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, finding the best mattress without fiberglass is not always an easy task. For that reason, we’ve put together this roundup of the best mattresses without fiberglass. The majority of these mattress are eco-friendly and organic as well, which we will outline in our mini reviews on each one. We’ll also discuss the use of fiberglass more thoroughly in our guide at the bottom.

In addition to being fiberglass-free, we made sure to include mattresses that can work for a wide variety of sleepers. This means testing mattress based on their pressure relief, firmness, motion isolation, cooling, and edge support. We’ve also included mattresses that are specifically geared toward heavy sleepers (those over 250 pounds) and various sleeping positions. This includes side, back, stomach, and combination sleepers (those who like to switch positions throughout the night). No matter what your preference, we’re positive you’ll be able to use the information we’ve derived from our tests to find the best fit. Read more below to find out which fiberglass-free mattress will match your individual needs.

Best Overall – Bear

Expert Opinion

The Bear is one of the only mattresses made specifically with athletes in mind. The secret? Celliant material in the cover. Some 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. It must be added at check out for an additional $130.

When we tested out the Bear, we were struck by its slightly firmer and supportive feel since it’s an all-foam mattress. We rated the Bear as a 7 on the firmness scale, which is created using the rankings of multiple Sleepopolis mattress testers. Because of this firm feel, the Bear gave us the sensation of sleeping on top of the bed, rather than sinking too far into it. That’s a mighty feat for a foam mattress, as foam bed usually tend to feel less supportive and durable than hybrid mattress or ones made from innersprings.

What our tester says: “The firm support of the Bear made me feel really comfortable while back sleeping. The bed kept me propped up, but the foams also offered nice sinkage and pressure relief around my lumbar region.” – Bridget Chapman, senior product editor

What Customers Say

After looking at the Bear website, the majority of reviewers commented on how well this mattress works for their younger children who are involved in athletics. Other users commented on how surprised they were by the comfort of this mattress despite the low price of the Bear.

Pros of the Bear

• The Bear is great for budget-friendly shoppers. Even before discounts, the Bear is priced under $1,000 for a queen-sized mattress.
• The Bear includes a two-inch section of graphite gel-infused memory foam, which has a slow-response to pressure. This is great for sleepers with back or joint pain, who will appreciate the contour and pressure relief that this mattress provides.
• With great motion transfer results, couples shouldn’t be able to feel the movements of their partner throughout the night. This is due to the top layer of memory foam included in the Bear, which keeps movement from spreading across the top of the mattress.

Cons of the Bear

• Heavier sleepers (those over 250 pounds) may not find the support they need from the Bear. Instead, these sleepers might want to opt for an innerspring mattress, which they can find in our roundup of best innerspring mattresses.

Bear’s Fiberglass-Free Construction

Bear says on its website, “None of our mattresses contain fiberglass. We use 100% fiberglass-free, OEKO-TEX certified, flame-retardant rayon. It’s chemical-free, safe, and effective, so you can breathe easy at night.”

Best Latex Mattress – Nolah Natural

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.

The cover of the Nolah Natural includes organic wool that’s moisture-wicking and creates a natural fire barrier. This is especially important for a mattress that does not contain any fiberglass. The hybrid construction of the Nolah Natural also allows for more airflow throughout the mattress, helping with breathability and preventing the build-up of body heat.

What our tester says: “I felt so cozy on the Nolah Natural. Its two layers of latex kept me propped up and supported, but also offered some nice contouring around my joints. I think combination sleepers could really enjoy this bed too since it’s easy to move around on.” – Bridget Chapman, senior product editor

What Customers Say

Many folks on the Nolah website commented on how much they appreciate a mattress made from entirely eco-friendly materials. Other users stated that the Nolah Natural was more comfortable than hotel mattresses that they have slept on in the past.

Pros of the Nolah Natural

• Heavier sleepers that prefer to sleep on their side or back should enjoy the support and pressure relief that the softness of the Nolah Natural offers.
• Sleepers with back pain should appreciate the pressure relief that the Nolah Natural offers. Our Sleepopolis mattress testers spread a pressure map over the bed and lay in different sleeping positions, showing how much pressure is exerted on the mattress. For back sleeping, the pressure map was completely blue (meaning low pressure).
• Since the Nolah Natural includes coils and latex in its hybrid construction, it is a good mattress for sex because it is bouncy and responsive to movements on top of the bed.

Cons of the Nolah Natural

• This is a soft mattress, so strict stomach sleepers will want to opt for a firmer mattress that will keep their hips lifted in line with their shoulders, promoting a healthy spinal alignment. Take a look at our best mattresses for stomach sleepers to find a firmer mattress.

Nolah’s Fiberglass-Free Construction

The company says on its website, “Nolah is committed to our customers’ comfort and safety, and all our mattresses are 100% fiberglass-free. Rigorous testing and strict certifications demonstrate the safety of all materials used in our mattresses. Our AirFoam™ mattresses (Nolah Original, Signature, and Evolution) are CertiPUR-US® certified and free from ozone depleters, heavy metals, and chemical fire retardants. Our latex hybrid mattresses (Nolah Natural and Nurture) are Global Organic Textile Standard (GOTS) and OEKO-TEX 100 Class 1 certified; they test free of harmful chemicals and substances.”

Best Mattress for Back Sleepers – Helix Midnight Luxe

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.

However, back sleepers also need pressure relief around their lumbar region and shoulders. The comfort layer included in the Helix Midnight Luxe is made of memory foam, which helps to relieve added pressure around the joints and contour the body where it needs it most. This hybrid mattress also sleeps cool and has high breathability, offering an added bonus to sleepers that might suffer from night sweats, or to those who sleep with a partner and have double the body heat in their bed.

What our tester says: “I really like this bed for combination sleepers. The mattress is bouncy, making it easy for you to roll over or switch positions at night without worrying that you’ll get “stuck” in the bed. I think the luxe version is a great option for anyone looking to have all the benefits of the original mattress model — but with added plushness and support.” – Bridget Chapman, senior product editor

What Customers Say

Many customers on the reviews section of the Helix website praised the Helix Midnight Luxe for its plush feel, with some comparing it to sleeping on a cloud. Other users also noted how well this mattress helped to alleviate their back pain, which many attributed to the pillow top included on the Helix Midnight Luxe.

Pros of the Helix Midnight Luxe

• Sleepers who suffer from shoulder pain should feel comfortable on the Helix Midnight Luxe because it includes cushioning that prevents stiffness around the joints. This same cushioning also helps to relieve hip pain. However, side sleepers with hip pain might want to check out a softer mattress for more cushioning.
• The Helix Midnight Luxe does a great job isolating motion, which can be seen in the motion transfer test results. This is great for couples because one partner shouldn’t be able to feel the movement of the other during the night.
• The Helix Midnight Luxe is also a great mattress for sex because of the bounciness of the individually wrapped coils included in its construction. This makes the bed easy to move around and switch positions on top of.

Cons of the Helix Midnight Luxe

• Heavier sleepers (those over 250 pounds) most likely won’t get the support they need from the Helix Midnight Luxe because of how soft this mattress is. These sleepers will need to opt for a mattress designed for larger body types, which they might be able to find on our best mattresses for heavier sleepers page.

Helix’s Fiberglass-Free Construction

Helix says on its website that “Every Helix mattress is made without the use of fiberglass. All Helix mattresses are designed with a fire retardant yarn made from a chemical-free Rayon barrier that is in the form of a small foam layer. Rayon fiber is a manufactured fiber composed of 100% regenerated cellulose.”

Best for Heavy Sleepers – Titan Plus

Expert Opinion

The Titan Plus’s mighty name alludes to the fact that the mattress was designed for sleepers over 250 pounds. In fact, the company says the mattress can support up to 1,000 pounds for couples or those who bed-share. The mattress has many layers, starting with a quilted gel foam top and ending with six inches of sturdy coils and two inches of high-density base foam. The Titan Plus ranked at a 7.5 on our firmness scale, so it’s firmer than most other beds on the market. However, heavier sleepers should also get pressure relief in addition to stability and durability.

Couples should also appreciate the construction of this mattress, since a bed with two people is going to need extra support. Luckily, the Titan Plus is specifically designed with strong edge support. Our Sleepopolis testers did not feel any sagging or sinkage when they sat on the edge, which is great for couples who like to spread out and use the entire surface area of their mattress.

What our tester says: “With 6.5 being the industry standard for medium-firm, this is definitely a firm mattress. I didn’t sink into the mattress. I was comfortable, but I certainly didn’t feel like I was becoming “part of the bed.” In fact, I found it quite easy to move between different positions.” – Bridget Chapman, senior product editor

What Customers Say

Many couples wrote on the Titan Plus website that they loved how they could sleep soundly throughout the night without feeling any movement from their partner. Many users also loved the stability the Titan Plus brought them, especially as heavier sleepers, which is exactly who this mattress is meant for.

Pros of the Titan Plus

• Sleepers with back pain should appreciate the Titan Plus’s support, which will help to keep their spine in alignment during the night.
• The Titan Plus did well on our responsiveness test. It should be easy to move around the mattress, which is great news for those wanting a good mattress for sex or combination sleeping.
• Couples should appreciate the Titan Plus’s motion transfer results. With good motion isolation, couples shouldn’t feel the tossing and turning of their partner during the night.

Cons of the Titan Plus

• Strict side sleepers with joint pain will want to go for a softer mattress in order to get more pressure relief around their hips and shoulders. Take a look at our roundup of the best mattresses for hip pain.

Titan Plus’s Fiberglass-Free Construction

3Z Brands’s CEO John Merwin speaks on behalf of all 3Z mattresses (including the Titan Plus): “Instead of spraying on fire retardant chemical sprays, we ensure that all 3Z Brand mattresses are fire safe and fiberglass free by using fire resistant fabric quilted into the mattress panels or by casing our foam in high quality fire retardant socks.”

Best Organic Mattress – Birch

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.

The Birch is constructed using organic cotton and wool fibers. It is Greenguard Gold certified, so this mattress wasn’t made using high levels of chemical emissions or volatile organic compounds. The quilted fibers in the Birch also make the material fire-retardant, which is great for a bed that does include any fiberglass in its construction.

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.” – Madison Schaper, former Sleepopolis staff writer and mattress tester

What Customers Say

The majority of customers on the Helix website commented on how little back pain they had after spending a few nights sleeping on the Birch. Other users talked about how much they appreciated the natural materials used in the Birch, and Helix’s commitment to eco-friendly mattresses in general.

Pros of the Birch

• The organic materials and pocketed coil system used in the construction of the Birch make it particularly breathable, which is great for both hot sleepers and couples who want to make sure they don’t wake up sweaty. The natural wool used in the Birch also prevents this mattress from trapping any body heat, adding to the cooling feel.
• The Birch is great for lightweight sleepers who don’t want to “sink” into their mattress. Lightweight back and stomach sleepers should especially enjoy the Birch because it should keep them uplifted so their hips can stay in line with their shoulders, promoting a healthy spinal alignment.
• The Birch is also a great mattress for sleepers who suffer from back pain because of its results on our pressure map. While on our back, the results lit up entirely blue during the pressure map test (meaning low pressure), so sleepers with back pain should be comfortable.

Cons of the Birch

• Sleepers suffering from hip pain will need a softer mattress than the Birch. The longer you lay on this mattress on your side, the more pressure digs into your shoulders and hips, which can be seen during the pressure map test. Because of this, side sleepers with hip pain might want to check out our roundup of the best mattresses with pillow tops to get some added pressure relief for their joints.

Birch’s Fiberglass-Free Construction

The company says they don’t rely on plastics or fiberglass materials for the fire-retardant layer in their mattresses. “There are numerous benefits of wool in our organic mattresses. Not only is it extremely comfortable, but wool fibers also provide a natural insulator so your body temperature stays regulated, and you stay asleep all night,” its website says. “In addition, our wool is naturally flame-resistant which makes it one of the safest fire-safety fibers to use in a mattress.”

Best Cooling Mattress – Brooklyn Bedding Aurora Luxe

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.

There are also three separate firmnesses shoppers can choose from: Soft, Medium, and Firm. So, you can select the bed that’s best for your body weight and sleeping preferences. For what it’s worth, we tested the Firm.

What our tester says: “My favorite thing about this bed is how cooling it is. Even some of the best soft mattresses tend to sleep a little hot because of the snuggly foams they use. The Aurora Luxe really solves this problem with Phase Change Material and breathable pocketed coils. So hot sleepers who enjoy a soft feel should definitely check it out.” – Bridget Chapman, senior product editor

What Customers Say

The majority of reviews on the Brooklyn Bedding Aurora Luxe website talk about the overall good value. Some think the Aurora Luxe is a bit expensive, but state that for the luxurious features and high level of comfort, it’s a fair price.

Pros of the Brooklyn Bedding Aurora Luxe

• The Brooklyn Bedding Aurora Luxe is a great mattress for sleepers suffering from back pain. The top layer of foam included in the construction of the mattress helps to keep the spine in a neutral position, while also filling in the added space around the lower back. Additionally, the sturdy coils give extra support to the mattress.
• Back sleepers with hip and shoulder pain should find adequate pressure relief on this mattress.
• The Aurora Luxe is a great mattress for couples, as it scored well in motion isolation, responsiveness, cooling, and edge support.

Cons of the Brooklyn Bedding Aurora Luxe

• Most back and stomach sleepers over 250 pounds might find that the Brooklyn Bedding Aurora Luxe isn’t supportive enough. Instead, they should opt for one of the mattresses on our roundup of the best mattresses for heavier sleepers.

Brooklyn Bedding Aurora Luxe’s Fiberglass-Free Construction

3Z Brands’s CEO John Merwin speaks on behalf of all 3Z mattresses (including the Brooklyn Bedding Aurora Luxe): “Instead of spraying on fire retardant chemical sprays, we ensure that all 3Z Brand mattresses are fire safe and fiberglass free by using fire resistant fabric quilted into the mattress panels or by casing our foam in high quality fire retardant socks.”

Best for Stomach Sleepers – Saatva

Expert Opinion

The Saatva Classic is a luxury mattress with a traditional innerspring feel that comes in three different firmness levels: Plush Soft, Luxury Firm, and Firm. This mattress also comes in two different height options (11.5 inches and 14.5 inches) so you can pick exactly the right fit for your preferences. We tested out the Luxury Firm (a firmness of 7), but stomach sleepers might feel even more supported by the Firm version.

Even with the Luxury Firm version, we felt supported by its coil-on-coil construction. As a durable, sturdy innerspring, we think that the firmest version of the Saatva should keep stomach sleepers’ hips elevated and in proper alignment with the rest of the spine.

What our tester says: “I think those who appreciate a traditional innerspring feel will really like the Saatva. It offers a blend of cushioning and ample support, which helped maintain my spinal alignment and kept me comfortable.” – Bridget Chapman, senior product editor 

What Customers Say

The majority of reviews on the Saatva website comment on the stellar customer experience they received during their mattress search. Users spoke on how easy and convenient the white-glove delivery of the mattress was, and many customers commented on how nice it was to be able to sleep on their mattress the first night it was delivered, without having to wait for it to decompress (unlike many other mattresses on this list, the Saatva doesn’t arrive in a box).

Pros of the Saatva

• Because of the coil-on-coil design of Saatva, this mattress is especially bouncy. This is great for combination sleepers who want to switch between multiple different sleeping positions during the night. They should be able to move around easily on top of the Saatva.
• Heavier sleepers (those over 250 pounds) should enjoy the sturdy construction of the Saatva. The materials used allow for a stronger mattress that will stay durable for longer.
• The reinforced edge support system combines coils and polyfoam, creating strong edge support. This is especially important for couples who want to spread out on their mattress without fear of rolling off or sagging.

Cons of the Saatva

• The Saatva might be too firm for strict side sleepers. These sleepers might want to opt for the Plush Soft model of the Saatva instead, especially if they are also lightweight sleepers who need extra pressure relief for their shoulders and hips. If this sounds like you, check out our best mattresses for side sleepers for other options.

Saatva’s Fiberglass-Free Construction

The Saatva’s cover is made of organic cotton and has an antimicrobial treatment. On its website, the company says, “While not 100% organic, the Saatva Classic mattress incorporates organic components and other eco-friendly features, including a 100% organic cotton cover with a plant-based antimicrobial treatment; Certi-PUR foams that are certified to be low-VOC and contain natural ingredients derived from soybean and corn oil; a natural thistle flame barrier in place of chemical flame retardants; and recycled steel in the support coils.”

Best Hybrid Mattress – Awara Natural

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 Awara Natural Hybrid, 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 a fairly firm and responsive mattress, giving it a score of 7.5 out of 10 on our mattress firmness scale. That means the Awara Natural Hybrid is a bit firmer than most other beds, as the industry standard is set at 6.5 for a medium-firm mattress. 

In terms of being eco-friendly, the Awara Natural Hybrid really has everything. This mattress is made completely free of lead, polyfoams, synthetic wool, and formaldehydes, as well as being free of fiberglass. The cover of the Awara Natural Hybrid is made from GOTS-certified organic cotton and 100 percent organic New Zealand wool. Even the latex used in the construction of this mattress combines GOLS-certified natural Dunlap latex and Rainforest Alliance certified latex. Finally, Awara plants ten tree for every mattress that they sell.

What our tester says: “The mix of bouncy latex with firm pocketed coils could be a winning combo for combination sleepers who switch from their back to their stomach. In general, if you’re after a bouncy mattress, you could find a lot to love in the Awara.” – Bridget Chapman, senior product editor

What Customers Say

After reading the customer reviews on the Awara website, the majority of users comment on the support they received from the Awara Natural Hybrid. Some customers also commented on how cool this mattress sleeps compared to the majority of mattresses they have used in the past.

Pros of the Awara Natural

• The firmness of the Awara Natural Hybrid makes it a great option for stomach sleepers who need some extra support. This mattress will help keep the stomach sleepers’ hips in line with their shoulders, which promotes a healthy spinal alignment.
• Heavier sleepers (those over 250 pounds) should appreciate the firm feel of the Awara Natural Hybrid. It’s good for most heavy sleepers who choose to rest on their back or side, as its support will keep them elevated. However, heavier stomach sleepers might need a little more support than this mattress can offer.
• The organic cotton and wool used in the top layers of the Awara Natural Hybrid, and the natural latex and pocketed coils in its construction, all help to regulate temperature. This is great for hot sleepers and couples who want to stay cooler throughout the night.

Cons of the Awara Natural

• The latex and pocketed coil combination included in the construction of the Awara Natural Hybrid make this mattress very bouncy and responsive, which is not great for motion transfer. Couples will most likely be able to feel each other moving around at night, which could be frustrating for light sleepers with restless partners. Check out our roundup of the best mattress for couples to find mattresses with better motion transfer results.

Awara’s Fiberglass-Free Construction

An Awara company representative tells Sleepopolis, “All Awara and Awara Premier mattresses are built to meet federal fire safety regulations and do not contain silica or glass fiber in any component of the product.”

Best Firm – Minocasa

Expert Opinion

Mattresses have a wide range of lifespans, but regardless of how long yours lasts, it’s always a little nerve-racking to cough up the money for a new one. Out of all of the considerations, perhaps the most important is the balance between a mattress that’s high-quality, yet set at a fair value. With the Minocasa, you get both. For a queen, the “Mino Hybrid” is priced at $899, but with discounts, it brings things down to about $450.

During testing, we found this to be a firmer mattress (about an 8 out of 10 on our firmness scale), which is higher than the mattress industry standard for medium firm. The Minocasa has more of an “on top of” feel with a thinner comfort layer, so it appeals to combination sleepers who want to be able to move freely and switch positions often on top of the mattress.

As a hybrid mattress, the Minocasa is made out of spring pockets and memory foam. Obviously, this mattress is fiberglass free in order to be on this list, but the Minocasa’s foams are also CertiPUR-US certified, making it even more environmentally friendly for its users.

What our tester says: “I would consider the Mino Hybrid a great option for back and stomach sleepers who prefer a firmer mattress. It is also responsive, cooling, and has decent edge support, making it a good option for couples who prefer a firmer mattress. Above all, I think it’s a great budget option with proper materials.” – Bridget Chapman, senior product editor

What Customers Say

Reading the reviews on the Minocasa mattress, the majority of customers were thrilled with the quality of this mattress when compared to the low price, especially as it is an eco-friendly mattress as well. Other users commented on the firmness that extended all the way to the edge, allowing them extra room to sleep.

Pros of the Minocasa

• The Minocasa is a great option for stomach sleepers because of how firm it is. Strict stomach sleepers need a firm mattress in order to keep their hips in line with their shoulders. This helps these sleepers keep their spine in a healthy alignment throughout the night.
• Heavier sleepers (those over 250 pounds) will appreciate the Minocasa because it will feel slightly less firm to them. That means that these sleepers will still get the stability they need, while also feeling comfortable and supported. Both heavy back and stomach sleepers should sleep well on this mattress, but heavy side sleepers may still need something softer.
• The Minocasa is constructed with cooling gel in its memory foam layer, which can help alleviate extra body heat. As a hybrid mattress, the coil layer allows for added airflow, so hot sleepers should feel more breathability in this mattress. As an added bonus, the Minocasa includes a cover made of Tencel material, which is known to help keep sleepers cool.

Cons of the Minocasa

• The Minocasa is mostly likely going to be too firm for the majority of side sleepers. They need more pressure relief on their hips and shoulders, which they will likely not receive from this mattress, since the majority of the pressure map test lit up red (meaning high pressure) in this high position. Take a look at our roundup of the best mattresses for side sleepers for some better options.

Minocasa’s Fiberglass-Free Construction

On the Mino Hybrid page of the Minocasa website, you can find the company’s fiberglass statement in its FAQs: “No, our mattress does not contain any fiberglass.”

Best Pillow Top Mattress – Avocado Green

Expert Opinion

The Avocado Green mattress — an environmentally friendly latex hybrid — comes in both a Standard and Pillow Top version. We personally love the Pillow Top model because it has two inches of latex up top for added comfort, making it 13″ in comparison to the 11″ of the Standard model. Because of this, the mattress ranks at a 6 on our firmness scale, making it slightly softer than the industry average (which is set at 6.5 for a medium-firm mattress). However, if you opt for the Standard model, this mattress will likely feel firmer because you will be closer to the pocketed coils system underneath.

Along with being free from fiberglass, the Avocado Green is built with organic cotton, natural latex, Global Organic Textile Standard (GOTS) wool, and pocketed coils, making it extra eco-friendly. While these materials are great for eco-friendly shoppers, those on a budget might want to find a mattress that is slightly less expensive (which we’ll touch more on in the cons section of this review).

What our tester says: “I really liked the Avocado Pillow Top model! My favorite thing about it is how its slightly softer feel works for multiple sleeping positions and brings an added touch of luxury to the bed.” – Bridget Chapman, senior product editor 

What Customers Say

Most customers commented on the pressure relief they felt from the Avocado Green, with many saying the addition of the pillow top allowed them to sleep deeper for longer because of how comfortable the mattress was. Other users also commented on how this mattress helps to alleviate their joint pain, specifically in their hips and shoulders.

Pros of the Avocado Green

• Combination sleepers (especially those who switch between back and side sleeping during the night) should appreciate the bouncy feel of the Avocado, as it will allow them to stay “on top” of the mattress, making it easier to switch positions when needed.
• With the combination of latex and coils included in the construction of the Avocado Green, heavier sleepers (those over 250 pounds) should find the extra support and durability that they need from this mattress.
• The organic wool cover included in the Avocado Green contains a naturally cooling material that wicks away moisture from the body, so hot sleepers and couples with double the body heat in the bed should stay cooler for longer while sleeping on this mattress.

Cons of the Avocado Green

• Because of the added eco-friendly materials used in the construction of the Avocado Green, it is more on the expensive side, so it may not be the best pick for our more budget-conscious shoppers. Take a look at our best mattresses under $500 for more budget-friendly options.

Avocado’s Fiberglass-Free Construction

Avocado says on its website, “There are no flame retardants of any kind used in our Avocado Green Mattress or Avocado Latex Mattress. No toxic chemicals, no rayon, no fiberglass fiber ‘fire socks,’ and, of course, no boric acid or other undisclosed chemical treatments used on our organic materials. So how do we meet federal safety standards? We use 100% GOTS organic certified wool, which is naturally flame resistant, in just the right places.”

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.

Why Use Fiberglass?

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.

How To Look For Fiberglass In Mattresses

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. You can also check out our guide on fiberglass for more information.

• Look for organic materials in the mattress. Companies will often use organic materials, like cotton or wool, in the fire barriers of mattresses instead of fiberglass. 
• Ask the company if they use fiberglass in any form in their materials. 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.

Pro Tip: Trust Your Gut

If a company is dancing around the question and not being straightforward, trust your instincts and perhaps take your business elsewhere.

• Check the mattress label. It’s required for every new bed to have a tag that states all the materials used in it. 
• Avoid purchasing the cheapest option, if you can. 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.

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.

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.

How Body Type Can Make a Difference

Beds are typically going to feel firmer to lightweight sleepers than they do heavyweight sleepers. If you’re heavier in weight, you’re also going to need more support from a bed.

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.

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.

How We Chose These Mattresses

Our team of Certified Sleep Science Coaches has reviewed more than 220 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.
