Car seats contain flame retardants (TDCPP, TCEP, and other organophosphate chemicals), PFAS stain-resistant treatments, and off-gassing foam. A 2021 study found flame retardants in the blood of children who regularly used car seats. Children spend significant time in car seats, and the enclosed car environment concentrates chemical off-gassing.
