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
Despite its popularity, Graco's SnugRide line has been flagged by independent testing for elevated flame retardant levels. The SnugLock installation is convenient but does not address the chemical safety concerns.
