Do nursery crib mattresses contain flame retardant chemicals?

What's actually in it

Crib mattresses often contain organophosphate ester flame retardants and brominated flame retardants. These chemicals are added to meet flammability standards, but they don't stay put. They leach out of the materials and settle into house dust, where babies can breathe them in or ingest them through hand-to-mouth contact.

Even when furniture is replaced to meet newer standards, these chemicals can persist in the home environment, according to a 2026 study in Environ Pollut. You aren't just dealing with the mattress itself; you are dealing with a class of chemicals that move from products into the air and dust your baby breathes every day.

What the research says

The science is clear: these chemicals are not harmless. A 2026 study in Environ Pollut found that prenatal exposure to organophosphate ester flame retardants is linked to changes in child cognition. When these chemicals are present in the home, they can also impact behavior, as shown in a 2026 study in J Expo Sci Environ Epidemiol.

The risks extend to physical growth and immune health as well. A 2026 study in Environ Res linked gestational exposure to these flame retardants to changes in weight, height, and body mass index in children up to age 10. Furthermore, a 2026 study in Sci Total Environ identified an association between brominated flame retardants and the development of allergies in children. This is not just theoretical; it is documented, peer-reviewed research.
