Almost a third of our life is spent sleeping in our bed, and it’s important that our bodies can rest well and get a good night’s sleep.
In our countless hours of research when trying to determine the best foam mattress Canada, we came across startling information that many of the cheap foam mattresses contain fiberglass. We’ve also updated the information as mattress-in-a-box companies adapt and change in 2023.
Are fiberglass mattresses illegal in Canada? No they aren’t, and fiberglass isn’t needed to meet the Canadian fire restriction guidelines. So why do some companies still use fiberglass in mattresses?
It seems that as the mattres-in-a-box trend has increased, mattress companies have looked everywhere to cut costs. Mattresses with fiberglass is a cheap and easy way to pass the fire restriction guidelines in Canada, and even in the USA with their more strict requirements.

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 www.SaferProducts.gov.”
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.
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.”

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 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 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.

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 SleepEnvie Mattresses have Fiberglass?

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.
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.”
