Car seats are among the most chemically complex products in a child's life. Foam padding, plastic shells, and fabric covers can contain flame retardants (TDCIPP, TCEP), phthalates, and PFAS. Children spend hours restrained in these seats, often in hot cars where off-gassing accelerates significantly.
Why We Rated It This Way
Chicco is a popular mainstream brand but lacks transparency on chemical composition. The machine-washable cover is convenient but the fabric treatment status is unknown.
