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 has been flagged by the Ecology Center's HealthyStuff.org for elevated levels of halogenated flame retardants. The 4-in-1 design means children use this seat for many years — increasing cumulative exposure.
