Safer Car Seat Options -
In 2011, HealthyStuff.org performed testing that revealed the presence of toxic fire retardant chemicals in 44% percent of the 2011 car seats tested (results here). And more than half (60%) of the infant car seats tested contained at least one highly toxic chemical.
We used a Graco SnugRide 35 Infant Car Seat for the first 6 months which luckily had a low toxicity rating for our particular fabric as this study was only published after our child used the seat. We then purchased the Sunshine Kids Radian XTSL Convertible Car Seat as this is a high safety rated carseat and is the tallest seat on the market. Although the HealthyStuff.org testing did not include this particular model, the other Sunshine Kids models scored well including the Radian 80 model which is similar.
