What's in our fire barrier, and why it matters

The short answer: every Organix Bed mattress (Aria, Harmoni, Tranquiliti and Sereniti) uses the same fire barrier: organic cotton made with silica, which carries UL's GREENGUARD certification for low chemical emissions.

Every mattress sold in the U.S. has to pass a federal open-flame test (the Consumer Product Safety Commission's 16 CFR Part 1633). The layer that does that work is the fire barrier, a thin layer just under the cover. You never see it, but you sleep on it every night, so it's worth knowing what it's made of.

What a fire barrier does

A fire barrier helps a mattress resist an open flame long enough to meet the federal standard. Brands choose different materials for it. The standard sets how the mattress must perform, not which material a brand uses, so the only way to know what's in a given mattress is to ask.

What's in ours

We use one fire barrier in all four mattresses: organic cotton made with silica. Silica is the natural mineral found in sand and quartz. Woven with organic cotton, it lets the barrier pass the open-flame test.

The barrier carries UL's GREENGUARD certification, which means it was tested for low chemical emissions. GREENGUARD covers the fire barrier itself, not the finished mattress.

Around it, every layer has a job and a standard behind it:

Every mattress is handmade to order in our Salt Lake City, Utah facility, so we know what goes into each one.

How to read any mattress's materials

1. Find the law label. It's the sewn-in tag that lists materials by percentage. It's the quickest way to see what a mattress is made of.
2. Ask what the fire barrier is made of. A clear answer names the material, like "organic cotton made with silica."
3. Match each certification to its layer. A certified cover or foam describes that layer. Ask which certification covers the fire barrier. See our certifications page.
4. Ask to see the certificate. Brands that use certified materials can show you the documents.

Caring for your fire barrier

The fire barrier works best sealed inside the cover, so please don't remove the cover or the barrier. To keep your mattress fresh, use a removable mattress protector. A protector is also required for a return during the 90-night trial.

Common questions

Does every mattress have a fire barrier? Every mattress sold in the U.S. has to pass the federal open-flame test, and most do it with a fire barrier layer.

What is silica? A natural mineral, the main part of sand and quartz. In our barrier it's combined with organic cotton.

Is the fire barrier the same in all four Organix Bed mattresses? Yes. Aria, Harmoni, Tranquiliti and Sereniti all use organic cotton made with silica, GREENGUARD certified.

Can I wash the cover? Spot-clean only, and don't remove it. A removable protector is the easy way to keep things clean.
