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 Recommend This Product
The Doona is genuinely innovative and convenient, but the added mechanical complexity means more plastic components and less transparency on chemical composition. The convenience premium comes with a chemical uncertainty premium.
