I contacted a bunch of the “Bed-in-a-Box” companies selling memory foam and latex mattresses on the web and through Amazon and asked them these questions:
What I found regarding which Memory Foam Mattresses contain Fiberglass
Starting late September of 2019 I’ve been contacting memory foam mattress manufacturers. Most replies came in a day or two, some take up to 5 days, and a few don’t even bother to respond. Blank rows in the table below denote a memory foam mattress manufacturer that ignored me and didn’t respond to my questions.

Based on what I found the best Memory Foam Mattress brands that do NOT contain fiberglass are Amerisleep, Sunrising Bedding, and Tuft & Needle – but only if you are okay with Polyester or Rayon. The best fiberglass-free latex mattresses are Sleep On Latex and Eco Terra.
However, do not take my word as gold because people make mistakes and companies are known to lie! We have numerous examples in this article where companies said one thing but photos from Amazon reviews have shown the opposite. Always use due diligence and ask the mattress manufacturer for yourself and even demand to see a photo of the mattress label before ordering – if they can’t or won’t provide it, then perhaps they have something to hide.
To see more latex and memory foam mattress information and the actual responses to my questions made by Mattress manufacturers, see below.
AmazonBasics memory foam mattresses are made by various manufacturers so it would be hard to track down who made what, and even If I did it could change at any time. I would just play it safe and just always assume that an AmazonBasics memory foam mattress could contain fiberglass.
“Not only does the foam in Amerisleep mattresses meet the Certi-PUR® standards, but we also use plant-based materials instead of petroleum to make our foam. On top of that, our patented manufacturing process is the only one that meets the standards of the Clean Air Act. To clarify, our memory foam mattresses do not contain fiberglass, modacrylic, or silica in our covers. In addition, our mattresses are manufactured in the U.S.! “
So far so good… I will look for evidence that states otherwise, and I’m following up about the use of Polyester/Rayon and Fire Retardant sprays!
Amerisleep’s Second response:
“We wrap each mattress in a Greenguard Fire Sock to serve as a flame retardant. It uses a rayon fiber material from natural cellulose. It does not contain harmful chemicals and will keep you safe and healthy at night. Reports link Chemical Fire Retardants with serious health risks. Some of them include birth defects, behavioral problems, and hormone disruptions.”
Best Price Mattress
Best Price Mattress’ response:
“Our memory foam mattresses contain a silica based fire sock that encases the foam inside the mattress. Our materials are globally sourced in countries such as Thailand, Spain, Serbia, Vietnam, China and South Korea.”
A bit shady – Best Price mattress dodged the fiberglass question and stated their memory foam mattresses only contain silica when I contacted them, however their Amazon reviews show they do indeed contain fiberglass. Also, their website says mattresses are “Designed in USA” but fails to mention that it could actually be constructed in Canada, Europe, or USA.
Brentwood Home’s response:
“Our memory foam mattresses are made right here in our factory in Fullerton, CA. They do not contain fiberglass in any part of the mattress and we use hydrated silica as a fire barrier. I have reached out to our product specialist team about modacrylic and as soon as I hear back I will get back to you.”
The response from Brentwood is pretty favorable since hydrated silica is generally regarded as safe. I’m still waiting to hear back about Modacrylic and the use of Fire Retardant sprays.
Brentwood Home’s second response:
“Upon speaking with our Product Specialist Team, they informed us that these fibers are used in toxic fire retardants. We do not use any chemical fire retardants. Our Cedar luxe uses wool to encase the mattress on all six sides and the rest of our mattresses use hydrated silica interwoven into the underside of the mattress ticking.”
Casper Sleep’s response:
“None of our mattresses contain any of the materials you listed in your question above, nor do our mattress covers. Our mattresses are designed in the USA… Due to how we function, many of our products are manufactured locally per the domain… We operate in Europe, Canada and America currently, so it’s dependent upon where you purchase our mattress to an extent.”
However, Casper Sleep’s website FAQ clearly states:
“The Casper mattresses do not contain any flame retardant chemicals. Our flame retardant is a proprietary woven silica sock that’s just under the cover. In the event of a fire, the sock melts on itself and suffocates the oxygen needed for the fire to burn.”
It appears that Dreamfoam Bedding is owned and/or operated by Brookyln Bedding because that’s who responded to me via email after using the contact form on Dreamfoam Bedding’s website.
Dreamfoam Beddings’s response:
“We do not use any chemical fire sprays or chemical retardants in our mattresses. Brooklyn Bedding only uses the highest quality fire-retardant socks, made of Non-Woven Silica/Rayon/Polyester/Cotton Blend. For more information regarding our fire retardant fibers, you can research Jones Fiber. Our mattresses are made here in the U.S. in Phoenix, Arizona.”
While Eco Terra is technically a manufacturer of Latex mattresses and not memory foam I still decided to see what they had to say.
Eco Terra’s response:
“We source our latex in Sri-Lanka, but the mattress is assembled and handcrafted here in our warehouse in Camarillo, CA. The mattress does not contain any fiberglass, etc. It’s made of all natural latex, organic wool and cotton. We only use organic wool as natural fire barrier.”
“There are no harmful chemicals or fire retardants used in the manufacturing of the product. The only one with the fiberglass fire retardant and that is the 5″ gel memory foam mattress. The rest have a non removable cover… They are a treated cotton“
I must note that lots of Amazon reviews for Linenspa beds have complaints about bedbugs arriving in the package..
“Here is a list of mattresses that have a treated cotton fire-retardant cover instead of a fiberglass fire retardant:
5 inch Gel Infused Memory Foam, 6 inch Gel Infused Memory Foam, 8 inch Gel Infused Memory Foam, 10 inch Gel Infused Memory Foam, 10 Inch Plush Gel Infused Memory Foam”
“The inner cover of our memory foam mattress contains fiberglass… In addition, we are a large mattress manufacturer in China and our mattresses are also made in our factory in China.”
Nectar’s First response:
“None at all… NECTAR does not contain any flame retardant chemicals. Rather a proprietary sock that’s just under the cover. In the event of a fire, the sock melts on itself and suffocates”
Amazon reviews contain photos off Nectar’s memory foam mattress tags showing Rayon and Polyester in the used materials.
Nectar’s Second response:
“The proprietary sock does contain fiberglass”
So who knows, really? Nectar says one thing, evidence proves otherwise, and then they change their story when confronted an apologize for “misinformation”. It would be safest to just avoid Nectar completely in my opinion.
Puffy Mattress’ first response:
“Our mattresses are 100% made in the USA and are CertiPUR-US® certified. I have included two links below for more information on the construction of our mattresses and their materials.”
So in reality Puffy Mattress either avoided the question or they’ve hired lazy people to do support, because I had already been to the links provided and my question was not answered at all there which is why I emailed them in the first place… I’ve replied to their email, I guess we’ll see what happens!
Puffy Mattress’ second response:
“As we mentioned before, our mattresses are 100% CertiPUR-US certified. And you can check on the website all the materials that negate the certification, as well as what the foams have to go through to be certified. All the info that you need and asked bout is on their website: https://certipur.us/“
So Puffy got back to me and basically gave me the “as I said before” treatment with the same copy/paste reply as the first response. This has pissed me off a bit so I’ve replied one last time to give them a chance to actually answer my questions before I write them off as a member of the Avoid-At-All-Costs mattress brands.
Puffy Mattress’ third response:
“Thank you for your reply. It is stated under our “How Its Made” webpage that we do not use flame retardants. The foam layers are encased in a firesock that is comprised of silica and wool threads. The mattress has a polyester cover that completely encloses and covers the firesock.”
So after THREE emails Puffy finally gave the answers to my questions – answers which are definitely not on their “How It’s Made” page like the representative seems to believe. 🙄😐
“Sealy mattresses are designed and built in the U.S.A.”
Aside from revealing the country mattresses are manufactured in, Sealy dodged the other questions and didn’t reveal any info about Fiberglass use or Modacrylic/Silica/Rayon/Polyester.
Signature Designs (by Ashley)
Signature Sleep’s response:
“Ashley’s upholstered furniture is designed and labeled to comply with California’s TB 117-2013, and we are committed to designing our upholstered furniture with the goal of meeting the requirements of TB-117-2013 without the use of flame retardant chemicals. To that end, Ashley is pleased to announce that after working closely with our supply chain, upholstered furniture manufactured by or for us as of January 1, 2015 does not use flame retardant chemicals. In addition, all our upholstered furniture, no matter where it is shipped in the US, includes a label that complies with the requirements of California’s SB-1019”
Signature Designs by Ashley basically just dodged the questions and gave me the brochure copy/paste treatment. 🙄
Sleep on Latex
Sleep on Latex’s first response:
“We only sell latex mattresses that are made with 100% natural latex. There is no memory foam or synthetic latex added at all.
The liquid latex is harvested from rubber trees in Sri Lanka and the foam is made in and shipped from Malaysia.
Our latex does not contain fiberglass or any other similar materials in the cover or mattress. The cover is made with 100% organic cotton and 100% organic wool.”
Sleep on Latex seems to be a good choice! I have responded to their email and asked follow up questions just to make sure there are no fire-retardant sprays used, but seeing as wool is naturally fire retardant I think I already know that the answer will be “no”.
Sleep on Latex’s second response:
“Our mattress does not contain rayon, modacrylic, or silica. The cover has a zipper and the zipper tape is made of 100% polyester. Besides that, the cover fabric is 100% cotton and wool! We do not use any fire retardants. The wool in the mattress cover is enough to pass flammability tests.”
There you have it folks – no fire retardant sprays, rayon, and the only bit of polyester is the cover zipper which is why I’ve left the Sleep on Latex table entry as a “No” for polyester since most of the mattresses covered in this article probably have polyester zippers.
Signature Sleep’s response:
“Our Signature mattresses are manufactured in China… The FR barrier sock is made with a knitted process with 50% Modacrylic/50% Glass yarns (+/-10%). The Glass and Modacrylic yarns are used in the thread form on a small rolls and the final product is a kind of knitted (or woven) fabric.”
Signature Sleep was perhaps the most forthcoming of all the memory foam mattress manufacturers, they didn’t try to dodge questions and were the only manufacturer to give the amounts of Fiberglas and Modacrylic used based on percentages.
Sunrising Bedding’s response:
“We don’t have any fiberglass or chemical materials in the cover. Sunrising Bedding 8 inch and 10 inch mattress cover is made of pure Cashmere wool. Our mattress is manufactured in Malaysia.”
However, Sunrising Bedding’s website FAQ clearly states:
“The mattress is made in China. But it is CertiPUR-US certified that means it is made of safe materials and qualified for physical performance. We ensure it the same quality as U.S. mattresses.”
“As far as manufacturing is concerned, most of our products are made in Malaysia. Also, our mattresses contain no fiberglass at all. We took it off once the study suggests this material might be a health threat.Though the fiberglass material has been removed, our mattresses meet the requirements of 16 CFR Part 1633 (federal flammability (open flame) standard for the mattress sets) when used without a foundation, and meet the requirements of 16 CFR Part 1632 (Char length ≤ 2 inch in any direction of any cigarette).Meanwhile, our foam mattresses have undergone a rigorous certification by Certi-PUR US to be free from all harmful chemicals, carcinogens, PBDEs, heavy metal, phthalates, and formaldehyde. “
It’s good that Sweetnight removed fiberglass from their memory foam mattresses, however they still avoided answering the part of the question about Modacrylic, Rayon, Polyester, and FR Sprays like Antimony. I replied with follow up questions to get more information and will update when I get a response!
Tempur-Pedic completely dodged the questions and replied to me with a cookie cutter cut-n-paste reply that revealed no information about the country of origin nor materials used in their memory foam mattress manufacturing processes. They basically said it’s all a proprietary secret and that it’s legal and safe according to state and federal regulations.
Tuft & Needle
Tuft & Needle’s response:
“We manufacture our mattresses here in the US and do not use fiberglass, modacrylic, or silica in any components of our Original T&N or Mint mattress models… Our firesock is actually crafted with a polyester/cotton blend knit fabric, treated with a food grade salt.”
“All our mattresses contain glass fiber.”
Regarding where Zinus mattress are made their website states:
“Right now, our product designers are based in South Korea and our manufacturing factories are in Xiamen, China.”
Popular brands from Amazon that were skipped due to not having a website are: Olee Sleep, PrimaSleep, Ssecretland, Vesgantti, Vibe, and YiiYYaa. Nightsbridge by Corsicana was skipped because they’re not sold on Amazon like Corsicana’s other brands.
