No - Bear mattresses are fiberglass-free across every model line. Here's how Bear meets the federal open-flame standard without glass fiber, the certifications that back it up, and how to verify it on the law tag of any unit you buy.

No - Bear mattresses do not contain fiberglass. Every model in the lineup (Original, Original Hybrid, Pro, Elite, Star Hybrid, Natural, and the Bear Cub kids' line) is built without glass fiber in the fire barrier. Bear's own fiberglass-free statement confirms it, the brand's support article confirms it, and independent reviewers including NapLab, NCOA, and The Good Trade all verify the same thing. If your only question is the headline, that's the answer.
Read on for how Bear actually meets the federal flame-retardancy standard, what certifications back it up, and how to confirm it on the law tag of any unit you receive.
All mattresses sold in the U.S. must pass an open-flame test under 16 CFR 1633. Manufacturers can clear that bar three ways: chemical flame retardants (out of fashion), naturally fire-resistant fibers like wool or rayon-treated viscose, or a woven glass-fiber sock wrapped around the foam core. Glass fiber is the cheapest of those options, which is why budget brands often pick it.
The well-known risk - covered by Sleep Foundation and replicated in dozens of consumer-protection bulletins - only appears when the outer cover is unzipped or torn. Once that inner sock is exposed, glass fibers can spread through HVAC, clothing, and laundry, and remediation is expensive. That's the entire fiberglass conversation in one sentence.
Bear sidesteps that risk by not using the material in the first place.
Bear's fire barrier is a fire-retardant rayon-based fabric that the brand markets as WhisperShield. Per Bear's own WhisperShield disclosure, it sits inside the cover the same way fiberglass would in a budget mattress, but uses naturally flame-resistant fibers instead. NapLab confirms the construction is OEKO-TEX Standard 100 certified - meaning the textile is tested free of harmful chemicals.
On product pages, Bear states this directly. The Bear Original product page specifically calls out: "Meets strict fire safety standards (Federal Mattress Regulations 16 CFR 1633 and 1632) without the use of fiberglass fabric."
A "fiberglass-free" sticker on its own is just marketing. What makes Bear's claim verifiable is the certification stack:
Unlike some budget brands that disclose inconsistently across lines, Bear's fiberglass-free policy applies uniformly. As of 2026:
If a model is on Bear's site, it's fiberglass-free. There is no quiet exception line.
Bear sits in the mid-tier price band - more expensive than Allswell, Linenspa, or Zinus, less expensive than Saatva or Tempur-Pedic. The premium over the bottom tier is partly the fiberglass-free fire barrier, but it also includes Celliant-infused covers, copper-gel foams in the Pro line, and CertiPUR-US foams throughout. Reviewers at Mattress Clarity and CNET place the Bear Original as a strong value pick in the $700-$1,200 (queen) range.
If your priority is specifically fiberglass-free at the lowest possible price, Bear is one of the best options at this price tier. If your budget caps below $500 queen, the practical alternatives are Brooklyn Bedding, Tuft & Needle, and select Avocado promo runs - all of which we cover in separate guides.
No. Every model in Bear's current lineup - Original, Original Hybrid, Pro, Pro Hybrid, Elite Hybrid, Star Hybrid, Natural, and Bear Cub - is fiberglass-free. Bear's manufacturing facilities don't process fiberglass at all, which also eliminates cross-contamination risk between lines.
Bear uses a fire-retardant rayon-based fabric branded as WhisperShield. It sits inside the cover the same way a fiberglass sock would in a budget mattress, but uses naturally flame-resistant fibers - and is OEKO-TEX Standard 100 tested for harmful chemicals.
Bear's removable covers are designed to be washable per the brand's care instructions, which is itself a tell - fiberglass mattress covers come with explicit "do not unzip" warnings because removing them is the contamination event. Always follow Bear's specific wash instructions for your model.
Read the white law tag sewn to the side of the mattress. Bear units list rayon, polyester, viscose, and cotton blends - not glass fiber, fiberglass, or any rayon-glass blend. The certification badges (GREENGUARD Gold, CertiPUR-US) on Bear's product pages also serve as third-party confirmation.
No, but they're related. GREENGUARD Gold tests finished products for chemical emissions (VOCs, formaldehyde, phthalates), not specifically for fiberglass content. However, mattresses that pass GREENGUARD Gold typically can't include shedding fiberglass, because the test would catch the resulting particulate emissions. Combined with Bear's explicit fiberglass-free statement, the certification adds independent verification.
No. Class-action filings on fiberglass shedding have targeted budget brands (Zinus and several Amazon-only labels). Bear has not been named in any of those filings. As of publication, Bear has no current recall or fiberglass-related consumer-safety bulletin from the CPSC.
