The research by Ecology Center, a non-profit environmental group, was conducted on 150 seats in three categories. The 2011 model seats were tested for several chemicals that have been linked to developmental problems. However, researchers say the study is secondary to the car seat's primary purpose, as a safety device.
The most toxic infant car seats are the Graco SnugRide 35 in Edgemont red/black and Graco SnugRide 30 in Asprey. The least toxic: Chicco KeyFit 30 in Limonata, Graco SnugRide 35 in Laguna Bay and, the Combi Shuttle 33 in Cranberry Noche.
