Novaform - the Costco-exclusive memory foam brand - has been the subject of recurring fiberglass questions on Reddit, TikTok, and mattress forums. The short answer in 2026: Novaform mattresses do not contain fiberglass. A Novaform brand representative confirmed to independent testing lab NapLab on December 16, 2024 that all current Novaform mattresses are fiberglass-free, and the company's official product pages explicitly state the fire barrier uses safer alternatives. Below, we break down exactly what that means, what to check on older units, and how Novaform stacks up on broader safety certifications.
Does Novaform mattress have fiberglass?
No. All Novaform mattresses sold today - including the popular ComfortGrande Advanced 14", Serafina, SoFresh, and Legacy lines - use a fiberglass-free fire barrier. The company's official Legacy and ComfortGrande product pages call this out explicitly: "Designed with a fiberglass-free fire barrier" and "This mattress contains zero fiberglass." NapLab's mattress safety database, which has analyzed 395+ mattresses, lists Novaform as fiberglass-free as of the December 2024 brand confirmation, with the caveat that some legacy units sold before that period may have used different fire-retardant constructions.
What is fiberglass doing in mattresses anyway?
Federal flammability standard 16 CFR 1633 requires every mattress sold in the US to resist open-flame ignition. Cheaper memory foam beds typically meet this rule by wrapping the foam core in a knit "sock" of fiberglass strands. The sock works - but if a frustrated owner unzips the cover (most warnings against this are buried in fine print), the strands can shed and contaminate a home, triggering the kind of horror stories you see on r/Mattress. Brands that go fiberglass-free use rayon-silica blends, wool, or proprietary chemical-free barriers instead. That is the route Novaform takes.
What other harmful substances are in Novaform mattresses?
Beyond fiberglass, Novaform foams carry CertiPUR-US certification, an independent program that tests for a long list of substances of concern. CertiPUR-US foam contains:
- No formaldehyde
- No mercury, lead, or other heavy metals
- No ozone depleters (no CFCs)
- No PBDEs, TDCPP, or TCEP flame retardants
- Low VOC emissions (less than 0.5 parts per million)
Novaform mattresses are assembled in the United States, with covers sourced largely from overseas. Each model goes through clinical and durability testing before public release.
Are Costco Novaform mattresses being recalled?
As of May 2026, no active Consumer Product Safety Commission (CPSC) recall exists for any Novaform mattress sold at Costco. Most viral "Costco mattress fiberglass" videos circulating on TikTok refer to other foam brands sold at the warehouse - not Novaform. If you own a Novaform mattress and want to verify, leave the cover zipped (this is a general best practice for any foam mattress) and check the law tag for the model name and date code. Costco also accepts mattress returns at any time under its standard return policy if you want extra peace of mind.
Is Novaform mattress non-toxic?
By the standards most shoppers care about, yes. Non-toxic is not a regulated label, but Novaform meets the practical thresholds: CertiPUR-US foams, fiberglass-free fire barriers, no added formaldehyde, and low VOC off-gassing. New buyers should still expect a mild memory-foam smell for the first 24 to 72 hours - that's normal off-gassing of trapped air during compression shipping, not a chemical hazard. Air the bed in a ventilated room before sleeping on it.
How does Novaform compare to Casper on safety?
Both Novaform and Casper publish fiberglass-free constructions across their current lineups, and both use CertiPUR-US foams. The differences are structural rather than safety-based:
- Construction: Novaform is all-foam across every model. Casper offers all-foam, hybrid, and innerspring options.
- Pressure relief: Both excel for side sleepers thanks to memory foam contouring layers.
- Support: Casper hybrid models add zoned coil support; Novaform relies on dense base foam (3 to 3.5 lb/ft³).
- Price: Novaform consistently undercuts Casper, often by 30 to 50 percent at comparable thicknesses.
- Warranty: Novaform Legacy and ComfortGrande lines carry a 20-year limited warranty; Casper offers 10 years on most models.
Bottom line
If fiberglass was the only thing keeping you from clicking buy on a Novaform mattress at Costco, you can let it go. The brand is on the public, verified fiberglass-free list with NapLab and confirms it on its own product pages. Layer that with CertiPUR-US foam, low VOCs, and a 20-year warranty on flagship models, and Novaform sits firmly in the "safe to sleep on" tier of budget-friendly memory foam - provided you follow the universal rule: don't unzip the cover.
