Critical Exposure Risk — Why This Product Category Matters

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.
