Did you know you can buy a mattress without fiberglass? Despite fiberglass not being a necessity to meet Canadian fire safety regulations, numerous mattress-in-a-box companies still resort to its use.

In an effort to stay competitive and cut mattress costs in 2024, mattress companies often use fiberglass as a cheap fire barrier.

But as online mattress competition has increased, companies have had to get rid of fiberglass and still keep many of their mattress prices under $1000.

We’ve updated this information for 2024, and we’ve added new mattress companies that have just started up in Canada this year.

Why is there fiberglass in my mattress?

In response to concerns of chemical treatments being used in mattresses to meet fire-safety standards, mattress companies had to look for something else to use that made their foams fire-retardant, or a layer they could put around a foam mattress to make it fire retardant.

So much of the information found online is about mattresses destined for the USA market, and we know that Canada is not always the same. In fact, the flame test for mattresses in the USA uses a blowtorch, where as in Canada, the mattresses must only withstand a “cigarette burn” test before heading to market.

Of course, since a blowtorch certified mattress will also withstand a lesser smoldering cigarette, many mattresses that are marketed to the USA end up in Canada. That means that cheaper, imported mattress, could contain harmful chemicals or a fiberglass layer to meet the necessary blowtorch requirement.

Fiberglass is an inert substance that doesn’t burn. In addition, it’s cheap! It works as a fire proof wrapper for the mattress and it doesn’t cost very much to produce. (we have found some fiberglass-free mattresses under $1000).

These tight wrappers are made out of woven fiberglass that is designed to melt and encase the mattress during a fire to keep the mattress from burning.

Fiberglass is most commonly found in memory foam mattresses, as that type of foam is extremely flammable.

Is fiberglass in mattresses safe?

Sort of. The woven fiberglass is always part of the inner cover, inside the mattress cover. If undisturbed, it is relatively harmless. The Consumer Product Safety Commission even says it’s safe.

“CPSC staff is not aware of any health risks from the type of fiberglass used in textiles. This is a larger diameter continuous fiber. The type of fiberglass used in household insulation, which has shorter narrower fibers, may cause skin irritation on contact, or throat irritation if inhaled. Any concerns should be reported to”

However, over time, the fiberglass fibers can bend and break, and start poking through the outer cover. You can test by shining a flashlight horizontally along your mattress in a dark room, and if the fiberglass is poking through, you’ll see them glistening in the light.

Another problem, if you don’t notice the warning labels and decide to use the zippered on cover (yes, some mattresses with ‘do not remove cover’ warnings have a zipper on them!) and remove the outer cover, you can cause the tiny fiberglass fibers to become airborne and land on everything from clothing, to furniture, toys, and even wall-to-wall carpet. Clean up can cost thousands of dollars once that happens.

How can I tell if there is fiberglass in my mattress?

The mattress tag (you know that thing that says it’s illegal to remove unless you’re the customer?) will tell you if there is fiberglass in the mattress. Luckily, companies can’t really hide it under secret ingredients or different names.

What companies make a memory foam mattress without fiberglass?

There are many different companies that make mattresses without fiberglass. In fact, any mattress that is Made in Canada and sold to the Canadian market only needs to pass the cigarette test, and that can be done with much less harmful products like polyester, natural products like wool, or even unique treatments like Tuft & Needle’s salt treatment.

Keep reading to learn how specific mattress companies include, or avoid, fiberglass in their mattresses. So if you’re looking for a twin mattress without fiberglass, or a queen mattress without fiberglass, this list of mattress companies without fiberglass will teach you what you need to know.

Listed in alphabetical order:

Do Avocado Mattresses have Fiberglass?

Avacado Mattresses are not made with toxic fire and flame retardants. And since the mattresses are not made in Canada, they must meet the more harsh US flame proof standards. In the Avocado Green mattress and the Avocado organic latex mattress in a box, there are no flame retardants or synthetic “fire socks” used. They meet federal safety standards by using only organic wool. No other chemical treatments, rayon blends, or fiberglass fiber fire socks are used.

Do Bloom by SleepCountry Mattresses have Fiberglass?

The Bloom bed in a box by Sleep Country does not contain any fiberglass. In a chat with customer service, they said that in the USA there are federal requirements that require fire retardant, but in Canada, they don’t add any fiberglass or chemicals to their Bloom mattresses.

The parent company in charge of manufacturing, Primo International, also confirmed again in 2024 that the Bloom mattress does not contain any fiberglass nor any fiberglass protective barriers.

Do Cacoon by Sealy Mattresses have Fiberglass?

There is no mention of how the Cocoon mattress meets fire resistance requirements, and our only hint is that there is a cover that is ‘spot clean only’. That could mean there is a fiberglass sock underneath, or it could mean nothing. We’ve reached out to the company to find out, and we’ll update this when we learn more.

Do Casper Mattresses have Fiberglass?

All of the foam in Casper foam mattresses are CertiPUR certified. The website lists the Casper mattresses as being designed in California, but doesn’t list where they are made. In a customer service chat, I was told the mattresses are made by “carefully selected global partners”, and that can vary depending on where you are ordering the mattress from and which mattress you purchase.

Casper has an outer mattress cover made of recycled polyester, polyester, upcycled cotton, rayon, and lycra. It is not removable, and is spot clean only.

In a chat with a representative from Casper foam mattresses, when asked about fire-retardant ratings, was told there is a firesock under the outer mattress cover. “The [inner] firesock is composed of an inherently fire resistant (FR) rayon yarn with a fiberglass core, blended with small amounts of polyester and modacrylic. The fiberglass is fully encapsulated in the FR Rayon fiber, so no fiberglass should be exposed. In the event of a fire, these fibers are designed to char and form a barrier over the foam, preventing the flame from spreading into the foam layers.”

Casper has multiple mattress lines with prices ranging from $800 to $4500 for a queen size.

Do Cherry Mattresses have Fiberglass?

The Cherry budget foam mattress has a cover made with a 100% polyester. Since Canada does not require mattresses to be flame retardant the same way the USA does (and these are only sold in Canada), there is no need for fiberglass or flame retardants in the mattress cover or the mattress foam. The Cherry is a mattress without fiberglass.

Do Douglas Mattresses have Fiberglass?

Douglas mattresses are made with CertiPUR-US certified foam, so the foam doesn’t contain any harsh chemicals for flame retardants.

The cover is made out of a polyester viscose blend, and there is no mattress sock. In our Douglas Mattress Review we unwrapped the mattress to confirm that there was no fiberglass layer, and in fact the cover is removable and machine washable (something that fiberglass-containing mattresses tell you not to do).

There is no fiberglass in the Douglas mattresses. The mattress cover is made of polyester, tencel, elastene, and the bottom of the mattress is covered in polypropylene.

NOTE: This is for the Canadian market Douglas Mattress only. Douglas mattresses sold in the USA need to meet the higher flame retardant requirements and so the USA-market Douglas mattress DOES contain fiberglass

$799 for the Douglas Original in queen size, with the Alpine and Summer mattresses costing up to $1299

Do Emma Mattresses have Fiberglass?

Emma Mattresses are CertiPUR-US certified. That means that the mattress foams contain no toxic materials including formaldehyde, phthalates, flame retardants, and heavy metals.

On their website, Emma states that the Emma Original mattress is compliant with the Canadian fire safety regulations. They also note that they don’t use any chemicals to meet the requirement.

The Emma Climax Hybrid is constructed to comply with the applicable fire safety laws and is fire retardant. They go on to say that they “make sure to keep your safety in mind when engineering” their.

In a comment on Amazon, where Emma responded to a customer question about containing fiberglass, Emma responded with this: “We need to have a fire retardant sleeve (by law) however, this sleeve is not made of fiberglass but its rather made up of multiple different fabrics, including cotton.”

Do Essentia Mattresses have Fiberglass?

The flame-proof mattress test is only applicable in the United States, and at Essentia the mattresses our manufactured in their GOLS and GOTS certified organic factory in Canada. Since Canada does not have the same regulations in place, all mattresses shipped within Canada do not have the non-toxic Kevlar flame retardant fabric (even though it’s listed as one of the elements of their Tatami latex mattress).

In the United States, by using Kevlar (the same material used in bulletproof vests), Essentia organic latex mattresses meet all safety standards. Since Kevlar is a fabric, it is sewed onto the mattress like a sock. The material is not treated with any harmful chemicals, is non-toxic, and is safe for human contact. For mattresses shipped to the United States, you will see a mattress tag that notes the Kevlar fabric non-toxic fire barrier. We do not use any chemical flame retardant or spray any chemicals in our factory.

Do GhostBed Mattresses have Fiberglass?

Ghostbed doesn’t provide specific information about fiberglass in their mattresses. Digging into their FAQ page, we found this comment under the question “Are Ghostbed mattresses CertiPUR-US certified?”

  • Made without PBDEs, TDCPP or TCEP (”Tris”) flame retardants

In a chat with a GhostBed ‘sleep expert’ they confirmed that Ghostbed does not apply or use any chemicals to comply with the government’s fire regulations. They did, however, say that GhostBed uses a fiberglass scrim on the inside of the mattress (whatever a scrim is!).

Update: I used a dictionary, and a scrim is a strong, coarse material used for heavy-duty lining or upholstery. GhostBed uses a heavy, coarse material made of fiberglass on the inside of the mattress.

Do Hamuq Mattresses have Fiberglass?

There is no mention of fire retardants or how the Hamuq Hybrid mattress meets the flame resistant specifications set out by Health Canada.

In their FAQ section for their New Organic Hybrid Hamuq Mattress, Hamuq mentions that the 100% wool quilt layer of New Zealand Joma Wool acts as a natural fire retardant so they could avoid using chemical alternatives.

Do Haven Mattresses have Fiberglass?

In their FAQ section, Haven says that their mattresses don’t contain chemical fire retardants, and only mattresses ordered to the USA will have a kevlar sock – which is a chemical-free flame retardant required by US law.

Do Ikea Mattresses have Fiberglass?

Although specifically for the US (and since their is no entry for Canada, can we assume it’s the same?), IKEA says:
Mattresses/mattresses sets have a fibre fire barrier made of rayon/polyester batting with an inherently fire-resistant property. Flame retardant chemicals (non-halogenated phosphorous-based inorganic salts) are only used for some stitch bonds, piping and zippers on spring mattresses in the US.

Do Juno Mattresses have Fiberglass?

The foam inside the mattress is CertiPUR certified which means they are made without using harsh chemicals or flame retardants.

The Juno foam mattress has a cover made with a polyester viscose blend. The mattress cover does not contain glass fibers, but the cover is not meant to be removed – it is spot clean only.

With the proprietary materials used in the mattress cover, the fiber at the center of the yarn melts that leaves a protective lattice behind that physically prevents the fire from spreading into the foam core of the Juno foam mattress. Juno is a mattress without fiberglass.

Do Molblly Mattresses have Fiberglass?

Customer reviews from mattresses bought 2 years ago say that the Molblly mattresses do contain a fiberglass layer.

Most of their mattress listings on Amazon don’t mention anything about fiberglass or fire retardants. We did, however, find that on their most expensive mattress model, Molblly specifically say there is a fiberglass-free fire retardant layer.

They don’t give any more information on what that layer is made of, so we contacted them via their chat feature on their corporate website.

We asked if their mattresses contained fiberglass, and they answered by saying their mattresses are fiberglass free. We followed up asking for clarification.

Can you tell us what Molblly uses to make the mattress fire retardant if it doesn’t use fiberglass? The response was this: “According to the laws of furniture, all the mattress products are required to be fireproofing. And due to the immature technology in the past, only glass fiber can achieve the effect of fire prevention. But fortunately, now another better material has been found to replace fiberglass for fire protection, so our current mattresses don’t have fiberglass anymore.

We have asked what is in the fiberglass-free fire-retardant layer, and Molblly has not responded.

Do Nature’s Embrace Mattresses have Fiberglass?

Nature’s Embrace uses different options depending on the mattress and the destination. For all Canadian mattresses, the combination of organic cotton and wool, or Tencel and Polyester, is sufficient to pass all flammability standards set out by Health Canada. For American customers, they use a silica rayon barrier.

Do Naturepedic Mattresses have Fiberglass?

Naturepedic makes all of their mattresses without any chemicals, glues, or polyurethane foam. Their website stats that the mattress-in-a-box passes flame standards without any fire retardants or chemicals. We confirmed in a chat with their customer service that the mattresses don’t use any fiberglass to pass the flame standards.

Do Nectar Mattresses have Fiberglass?

Nectar mattresses probably uses fiberglass in their inner mattress cover to provide fire resistance. The mattress tag lists rayon and polyester as materials used, but a response directly from Nectar says that their proprietary mattress sock “does contain fiberglass”.

Do Octave Mattresses have Fiberglass?

Formerly called Novosbed, the company recently rebranded to Octave in Canada (they still operate as Novosbed in the USA).

The Octave memory foam mattresses do not contain any fiberglass.

This is what their customer support had to say: “Our Octave mattresses are Certipur-us certified and in order to produce safe to use and high-quality mattresses, that also comply with federal regulations, our mattresses do not incorporate PBDEs, TDCPP or TCEP fire retardant materials in their composition as they have proven to be harmful to human health and/or the environment.

Do Simmons Beautyrest Mattresses have Fiberglass?

Simmons doesn’t contain any information about fiberglass or fire retardants on their website so we reached out to their customer support. This is the information they responded with:

We do use a fire-retardant barrier system on all of our mattresses. The Simmons’ Beautyrest SIMGARD™ fire retardant barrier systems are made from a blend of proprietary components, but they are composed primarily of cotton or other cellulosic renewable fibers and use no harmful chemicals or processes, including fiberglass.

One component of the fire barrier forms a char layer that helps to create a non-toxic barrier to oxygen which is needed for a fire. A second component, Kevlar, is a para-aramid fiber that combines strength and thermal protection, is used in protective gear for firefighters and the military, and is inherently flame resistant. The SIMGARD™ mattress fire barrier is non-toxic and its components are recognized by the Consumer Product Safety Commission (CPSC) and certify compliance with all applicable CPSC regulations as being safe for consumers. Simmons mattresses meet all applicable environmental, health, and safety standards. We do not apply any chemicals to our products.

Do Tuft & Needle Mattresses have Fiberglass?

Careful! Tuft & Needle does not use fiberglass in their mattresses, and they state it multiple places on their website. However, their Amazon-only brand the Nod by Tuft & Needle does contain fiberglass! According to their customer support:

The Nod Mattress is made exclusively for Amazon and that particular model contains a fire sock, composed of four inert fibers and is inherently flame retardant. This barrier is permanently installed around the foam core of our mattress which is then fully encased within the outer cover. One of these fibers is a continuous glass filament that is a type of fiberglass. It actually looks like a thread. This thread is not like the fiberglass found in insulation and does not come into direct contact with the skin.

So do Tuft and Needle mattresses contain fiberglass? No, the Original, Mint and Mint hybrid do not contain fiberglass. Instead, they use a fire barrier that is made out of a polyester and cotton blend. Tuft & Needle is a foam mattress without fiberglass.

In order to make it fire-proof, they treat it with food-grade salt that acts as a natural fire retardant by cutting off the oxygen supply to the flame. There is no fire-retardant chemicals or fiberglass used.

This fabric is permanently installed around the foam core of the mattress, and then it is fully encased within the outer cover. The outer cover is not removable for cleaning, so if that is a concern, Tuft & Needle recommends using a waterproof mattress cover.

Do Zinus Mattresses have Fiberglass?


In the summer of 2023, Zinus mattresses stopped using fiberglass. The mattress tags instead now say that the inner cover is made from 85% rayon, 10% PAN (Polyacrylonitrile) based Carbon, and 5% polyester.

Rayon is a fabric made from purified cellulose fibers (typically from wood pulp), but it is highly flammable unless treated by chemicals. Polyester is not highly flammable (src), but it will char and melt when ignited. Polyacrylonitrile can be made to be flame resistant and has good char-forming ability.

Some mattresses that ship from Zinus in Canada have a tag that states that even the inner cover is made from 100% polyester. This is likely because the Canadian requirements are less than that in the USA, allowing for a simpler (and cheaper) chemically treated polyester fire barrier.

Tag from Zinus Mattress with no fiberglass


Zinus is a very popular mattress, and there have been tens of thousands of them sold. It seems that Zinus is taking most of the heat for fiberglass mattress issues since these mattresses are everywhere. In July 2022, a proposed class-action lawsuit (source: CBSNews) was filed against the company by people who claim to have suffered health problems from the flame-resistant fiberglass fibers that were released from the mattresses.

Sometime later in 2022 or early 2023, Zinus updated their mattresses. Now, the zippered cover is locked closed, and the tags now warn against removing the mattress cover in order to prevent it from being removed. Their website includes a vague warning in the FAQs section under “Can I wash my Zines mattress cover” which then said that the cover isn’t washable, and removing it could “inhibit the fire safety barrier.”

20 thoughts on “Confidently buy a mattress without fiberglass in Canada in 2024”

    1. Hi Valerie, I’ve contacted Bloom again for updated information, and they still say there is no fiberglass in bloom mattress. See above in the Bloom section for details. Hope that helps!

  1. I bought my Zinus green tea memory foam mattress from in April 2023. Although the label says polyester only, it also says do not remove. But there is no zipper so it would be difficult to remove. My question is, how do I find out if there is really fibreglass under the cover, I don’t want it in my house if it’s got any. I don’t trust their label at all.

    1. That’s right around the time they stopped using fiberglass because of lawsuits. Most of their mattresses have a rayon fire barrier – but perhaps this is a more natural version (because of the green tea version?) that just meets Canadian fire proof standards with a simple treated polyester fire barrier?
      You could perform a flashlight test to see if there is any fiberglass coming through the cover, but that’s about all you can do…

  2. Just curious, why do you link out to mattress makers confirmed to have fiberglass like Casper and GhostBed instead of only linking out to fiberglass-free mattresses? That seems a bit confusing and potentially misleading.

    1. The Springwall website is confusing and doesn’t contain information about the specific mattress lines and their materials. After much digging we finally found the FAQ section and all that mentions is that the foam is CeriPUR-US certified.

  3. Does Fleep matrress use any fiberglass? I’ve had a fleep for 5 years. It’s been pretty decent actually, but the softer side (as expected) is starting to get TOO soft, while the firm side remains just fine. Comparatively speaking I still think it’s been a good value.

    I was thinking about performing some mattress surgery and removing the old soft 2” layer of memory foam and/or support foam, and just keeping the HD foam and doing a DIY mattress – but I didn’t want to start tearing it apart unless I was sure there was no fiberglass.

    1. The Fleep website only mentions that no flame-retardant chemicals are used in their mattresses, so we’ve reached out and we will update here if they respond to our fiberglass in the mattress question.

  4. I have a mattress from MLILY from 2017 and the inner cover seems to have glass fiber but it’s hard to tell! The model I have isn’t available anymore, but the newest models specially say the inner cover is “glass fiber free.” Still, it’s a little suspicious with the information available.

    1. What do you mean it seems to have glass fiber? What does the tags on the mattress say? They typically say if there is glass fibers in it, or at least they will have a ‘do not remove cover’ warning

  5. Hi. So does Zinus in Canada have it? I know there’s been a lot of talk about that in the US but I thought their laws were different to ours. I was reading in some forms that It’s not in use in the mattresses in Canada. Is this accurate? Second question. If it is in use in Canada, I guess it would be absolutely unsafe to cut the mattress? Thanks for your time and help

    1. Yes, Zinus in Canada does have fiberglass – they don’t need it to meet the regulations, but they make the mattresses in China for both the USA and Canada market so they all have fiberglass in them.

      What do you need to cut the mattress for?

  6. Thank you so much for the much needed information. Any suggestions for fiberglass free crib mattress other than ikea.

    1. Hi Shania,

      Thanks for the comment!

      Many of the companies on this list (from Canada) make crib mattresses also, and they use the same materials as the bigger mattresses. They’re probably more expensive than Ikea though. Companies I can think of are:

      Polysleep probably the best price for something clean.

      Naturepedic and Avacado, but they are higher end mattresses to start with.

      We’ll have to create a list of crib mattresses in the future… sorry I don’t have that info for you off hand!


    1. We contacted them and asked, and while we don’t know about ever, Bloom does not use any fiberglass in their new mattresses in Canada.
