It depends on the model. Current all-foam Tulo Bamboo and Lavender mattresses are sold fiberglass-free, but older Tulo Liv hybrids are flagged in owner complaints, and Mattress Firm has no brand-wide disclosure page. Here's how to verify your specific Tulo via the law tag.
Short answer: It depends on the model and when it was made. Tulo - Mattress Firm's house brand - markets its current mattresses as fiberglass-free, and the bamboo memory-foam Tulo explicitly advertises a "Fiberglass Free Cover" on its Amazon listing. But independent industry research has flagged Tulo hybrids as having historically used fiberglass as a fire barrier, and Mattress Firm itself has not published a clean, brand-wide disclosure page the way Sealy, Helix, or Leesa have.
If you own a Tulo today - or you're shopping one secondhand - the only reliable answer comes from the law tag sewn to your specific mattress. This guide walks through what the SERP actually says, the lineup as of 2026, and exactly how to verify your unit.
So the clean way to phrase it: Tulo is not a 'no-fiberglass guaranteed' brand the way Saatva, Bear, or Avocado are. It's a brand where the answer depends on which Tulo you have.
Two things drive the Tulo fiberglass searches:
We don't sell Tulo. That means we can answer this without the conflict of interest a Mattress Firm rep faces when the same question gets asked at their counter.
Tulo's current mattress lineup (sold through Mattress Firm and a few third-party retailers like Amazon and Walmart) breaks down roughly like this:
All-foam memory foam models
Hybrid models
The all-foam models are the ones currently marketed as fiberglass-free. The hybrids are the ones flagged by third-party sources, and the ones with the most owner complaints. Mattress Firm has been quiet about whether the current hybrid units use fiberglass, glass-fiber-free rayon, or another barrier - and as of 2026, they have no publicly published disclosure page clarifying it.
Federal law - 16 CFR Part 1633 - requires every mattress sold in the U.S. to pass an open-flame test. There are several legal ways to pass it:
Fiberglass itself is not toxic in normal use - the cover keeps it contained. The problem is what happens when an owner unzips the cover to wash it (a habit many of us have with our other bedding) or when the cover gets worn, torn, or pet-damaged. Glass-fiber fragments then become airborne and embed in carpet, drywall, HVAC vents, and clothing. NapLab and class-action filings have documented cases where families had to replace flooring and bedding after a single cover removal.
That's why 'does my mattress have fiberglass' matters even when the manufacturer says the fibers are 'safely contained.' The real question is what happens if the containment fails.
Every mattress sold in the U.S. is required to carry a law tag - that white tag stitched to the side or foot of the mattress that says 'DO NOT REMOVE UNDER PENALTY OF LAW.' (You can remove it as the consumer; that warning is for retailers.) The tag lists the material content of the cover and fill.
Look for these strings:
If your Tulo law tag lists 'glass fiber' anywhere in the cover or barrier composition, it has fiberglass. If it lists silica, rayon, or wool with no glass-fiber language, it doesn't.
A few other tells:
It's a personal call, but here's the framework we give Banner customers:
If you're shopping a Tulo specifically because of the price, these have similar entry points and publicly documented fiberglass-free fire barriers:
We carry several of these on the Banner showroom floor and online. The point isn't that Tulo is uniquely bad - plenty of $300 mattresses on Amazon still ship with fiberglass - it's that you don't have to settle for ambiguity at this price.
Current Tulo all-foam memory foam mattresses are sold as fiberglass-free, and the Bamboo line says so on the box. Tulo hybrids - especially older Tulo Liv units - have a documented history of containing fiberglass as a fire barrier, and Mattress Firm has not published a brand-wide disclosure that would let you skip the law-tag check. If your Tulo's law tag mentions 'glass fiber' or 'glass wool,' it has fiberglass; if it lists silica, rayon, or wool, it doesn't.
The safest move for a new buyer is to choose a brand that publishes its FR-barrier composition. The safest move for a current owner is to read the tag, leave the cover zipped, and use a quality mattress protector.
No. The 8-inch and 10-inch Tulo Bamboo memory-foam mattresses are sold with a fiberglass-free cover and CertiPUR-US certified foams. The Amazon listing for the Tulo Bamboo explicitly carries a 'Fiberglass Free Cover' label.
Older Tulo Liv units sold around 2019 are the model most often cited in owner forums as containing fiberglass. Mattress Firm has not published a clean disclosure for current hybrid Tulos either way, so the only reliable answer is to read your specific mattress's law tag and check for 'glass fiber' or 'glass wool.'
Tulo is the house brand of Mattress Firm. It launched as Mattress Firm's bed-in-a-box line and is sold primarily through Mattress Firm stores, with some SKUs on Amazon and Walmart. Mattress Firm has owned the brand since its launch.
Read the law tag - the white tag sewn to the side or foot of the mattress. Look for the words 'glass fiber,' 'glass wool,' or 'fiberglass' in the cover or fill composition. If the tag lists 'silica,' 'rayon,' or 'wool' instead, the mattress uses a non-glass fire barrier. Never unzip the cover to check directly; that's the exact action that can release fibers.
If the cover is intact and you don't plan to remove it, add a quality encasement-style mattress protector and continue using it normally - the risk is low when fibers stay contained. If the cover is already torn, frayed, or has been opened, bag the mattress, replace it, and wet-wipe hard surfaces in the room. Don't vacuum, which can disperse fibers further.
Yes. Nectar Classic, Bear Original, Leesa Studio, and Helix Twilight all publish fiberglass-free disclosures and sit in or near Tulo's price band. Saatva Classic is an innerspring option with a steel-coil core and no fiberglass at a slightly higher price.
We don't sell Tulo. We do carry brands that publish their fire-barrier specs - Saatva, Helix, Nectar, Bear, Tempurpedic, and more - so you don't have to read law tags to know what you're sleeping on.
