Extend2Fit Convertible Car Seat
One of the best-selling convertible car seats in the U.S. Rated F for chemical content — not for crash safety, which meets federal standards.
This is a rating of this specific product only — not the company. Other products from this brand may score differently.
Car seats are among the most chemically concerning children's products because infants and toddlers spend hours each day in direct contact with treated foam and fabric. The seat heats up in a warm car — temperatures above 85°F accelerate off-gassing of flame retardant chemicals into the air your child breathes. A 2022 Ecology Center study found hazardous chemicals in more than half of U.S. children's car seats. TCIPP, the flame retardant found in Graco seats, was classified as a probable human carcinogen by the International Agency for Research on Cancer in 2024.
Why We Rated It This Way
Independent testing by the Ecology Center detected TCIPP and halogenated flame retardants in the seat foam and fabric. TCIPP was classified as a probable human carcinogen in 2024.
