Zoma states every mattress it sells today is 100% fiberglass-free and CertiPUR-US certified. Here is what that means, what older Zoma owners have reported, and how to verify before you unzip a cover.
Short answer: No. Zoma states on its official FAQ that Zoma mattresses are 100% fiberglass-free and made with CertiPUR-US certified foams. Every model currently sold - Zoma Start, Zoma Hybrid, and Zoma Boost - uses a knit cover and inherent fire-barrier construction that does not rely on a glass-fiber sock.
That said, this question keeps coming up because a small number of older Zoma owners on Reddit have reported fiberglass-like shedding after years of use. Below we lay out what Zoma's current spec sheets and certifications actually say, what those user reports likely refer to, and the three checks any shopper can run in five minutes before pulling the trigger.
Zoma's customer FAQ states plainly: "Zoma mattresses are 100% fiberglass free and made with eco-friendly materials." That language is paired with CertiPUR-US certification, an independent program that tests every foam component for the chemicals shoppers most often worry about.
Specifically, CertiPUR-US verifies the foams contain no:
Independent reviewers including CNET (Mar 2025), Sleepopolis, NapLab, and EachNight have all confirmed the same answer when asking directly: no fiberglass in any Zoma mattress they tested.
U.S. mattresses sold to consumers must pass 16 CFR Part 1633, the federal open-flame test enforced by the Consumer Product Safety Commission. Cheap online foam mattresses often hit that bar by sewing a thin sock of woven glass fiber into the cover. Heat it long enough and the glass turns into a ceramic-like char layer that smothers the flames.
Zoma takes a different route. Its current covers are knit polyester-and-spandex (97/3) with a non-fiberglass fire barrier layered between the cover and the comfort foam. That barrier uses inherently flame-resistant rayon and silica-treated cellulose fibers - chemically distinct from spun glass - so even a torn cover does not release the itchy glass shards that have caused class-action complaints against other brands.
If you search "Zoma fiberglass" you will land on a 2021 Reddit thread in r/Mattress where one owner says their Zoma "started leaking fiberglass a couple years after purchase." The post has stuck around in Google's top results for years and is the single biggest reason this question is still asked.
Here is the nuance worth knowing before you panic:
That does not invalidate the Reddit user's frustration - a shedding cover is annoying regardless of fiber type. But it is a different problem than the fiberglass scandals you may have read about.
Fiberglass is mostly a feature of bargain-priced, foam-only mattresses sold through Amazon and big-box retailers. The brands that have been hit with confirmed fiberglass complaints share a pattern: sub-$400 queens, all-foam construction, white-label manufacturing, and aggressive "do not remove the cover" warnings.
Zoma sits one tier above that - direct-to-consumer, U.S.-manufactured, with retailer (Mattress Firm) accountability and a published 10-year warranty. The economics make designed-in fiberglass less attractive: a class-action settlement would cost more than the rayon-and-silica fire barrier Zoma actually uses.
If fiberglass is a hard "no" for your household - kids, pets, or chemical sensitivities - Zoma is a defensible choice. Saatva, Helix, Nectar, and Purple also publish fiberglass-free statements backed by CertiPUR-US documentation.
Zoma states that its mattresses have always been fiberglass-free. There is no public regulatory filing, CPSC recall, or class-action settlement linking Zoma to fiberglass shedding. Older Reddit reports of fibrous shedding are consistent with polyester or rayon fibers, not glass.
Zoma covers are a knit blend of approximately 97% polyester and 3% spandex. Underneath the cover is a non-fiberglass fire barrier made from inherently flame-resistant rayon and silica-treated cellulose fibers.
Yes. Zoma's care instructions explicitly allow unzipping the cover and machine-washing it on cold, then air-drying. Brands that use fiberglass print prominent warnings against removing the cover for that exact reason.
Check the white law tag sewn into the side of the mattress. If it lists "fiberglass," "glass fiber," or "glass wool," the mattress contains it. Also look for warnings against removing the cover and search the brand model in the CertiPUR-US directory.
Yes. Zoma states that all foam components in its Start, Hybrid, and Boost mattresses are CertiPUR-US certified, meaning they have been tested for restricted flame retardants, heavy metals, formaldehyde, phthalates, and VOC emissions.
Stop using the mattress, take photographs of the shed material, and contact Zoma customer support to open a warranty claim. Zoma's 10-year warranty covers manufacturing defects, including unintended cover failure. Do not vacuum the affected area until you have evidence preserved.
