Does replacing your sofa with a flame-retardant-free version actually lower your body burden?

What's actually in it

Older sofas and chairs often contain foam treated with halogenated flame retardants, including polybrominated diphenyl ethers (PBDEs) and newer halogenated alternatives. These chemicals don't stay locked in the foam. They migrate to the surface and become part of house dust. Vacuuming and normal handling break the foam surface further, releasing more particles.

People in homes with PBDE-containing furniture have higher blood levels of these chemicals. The furniture is a continuous daily exposure source.

What the research says

A 2026 study tracking flame retardant biomarker changes after furniture replacement found that replacing flame-retardant-containing sofas with furniture certified to meet flammability standards without added halogenated chemicals led to measurable decreases in flame retardant biomarkers in household members within months.

This is one of the cleaner demonstrations that removing a known exposure source produces a measurable biological benefit. The effect is strongest in children, who spend more time on the floor near furniture and have higher dust ingestion.

When buying new furniture, look for Greenguard Gold certification or TB 117-2013 compliance without added flame retardants. This is legal in all US states and doesn't compromise fire safety.
