No Avocado mattress contains fiberglass. Avocado uses GOTS-certified organic wool as a natural flame barrier instead - here's how that works and how to verify it.

Short answer: no Avocado mattress contains fiberglass. Avocado meets federal flammability standards using GOTS-certified organic wool - a natural fire barrier - instead of the woven fiberglass "fire socks" found in many budget bed-in-a-box mattresses. The brand confirms this directly in its help center and across its materials page.
U.S. federal regulation 16 CFR 1633 requires every mattress sold to resist open-flame ignition. Manufacturers can meet that standard with chemical flame retardants, woven fiberglass barriers, or naturally fire-resistant materials like wool. Fiberglass is cheap, effective, and undisclosed on most spec sheets - which is why budget memory-foam mattresses lean on it heavily. According to a Naplab analysis of 395 mattresses, roughly 10% of mattresses on the market still contain fiberglass.
Avocado's flame strategy is a single thick layer of densely packed, GOTS-certified organic wool sourced from the company's own farm. Wool is inherently flame resistant: it self-extinguishes and won't sustain a flame the way synthetic foams will. That removes the need for both fiberglass and chemical retardants.
Avocado's vegan models swap wool for a charcoal- and graphite-infused latex barrier - different chemistry, same outcome: no fiberglass and no synthetic retardants.

The Avocado Green and Avocado Vegan share the same core architecture, with the cover and flame layer being the main difference:
Avocado publishes its construction openly, but if you're cross-shopping or already own a mattress and aren't sure, three checks rule fiberglass in or out fast:
No. The Avocado Green Mattress uses GOTS-certified organic wool as its flame barrier. Avocado has publicly stated it does not use fiberglass, chemical flame retardants, or undisclosed chemical treatments in any of its mattresses.
The Avocado Vegan Mattress also contains no fiberglass. Because it omits wool for vegan reasons, it uses a charcoal- and graphite-infused latex flame barrier to meet federal flammability standards.
Yes. Because there is no fiberglass inner sock to contain, the cover is designed to be removed and spot-cleaned. That is generally not safe to do on mattresses that rely on a fiberglass barrier underneath the outer cover.
A 2023 class-action complaint alleged Avocado used some non-organic synthetic materials. The case did not allege fiberglass content, and was reportedly dismissed. Avocado's finished-product GOTS and GOLS certifications still prohibit fiberglass.
Independent testing finds fiberglass most often in budget all-foam mattresses sold via Amazon and big-box retailers - typically priced under $400 in queen size. Brands with finished-product GOTS or GOLS certification, or brands that explicitly publish a fiberglass-free statement, are the safest bets.
Check the law tag for glass fiber, glass wool, or high rayon/polyester percentages, and look for a 'do not remove cover' warning - a strong fiberglass indicator. When in doubt, contact the manufacturer for a written confirmation.
