IIHS Booster Seat Ratings
Finding the right booster seat for your child when they’ve outgrown their car seat is a lot easier with the Insurance Institute for Highway Safety (IIHS) annual rankings. The IIHS began ranking car seats in 2008 because their research showed most booster seats weren’t doing a good job of consistently or correctly positioning safety belts for children 4 to 8 years old. An improperly fitted seat belt can injure a child in an accident.
