Your child will love hopping into the car knowing the Chibi Justice League is along for the ride! The KidsEmbrace DC Comics Chibi Justice League High-Back Booster Car Seat has been rigorously tested and exceeds Federal Motor Vehicle Safety Standard (FMVSS 213), plus it was given a “Best Bet” rating by the Insurance Institute for Highway Safety. The high-back booster is approved for use by children over 3 years old, 30 to 100 pounds, and 38 to 57 inches in height. It easily converts from a high-back booster seat to a backless booster seat for children over 4 years old, 40 to 100 pounds, and 40 to 57 inches in height. The headrest adjusts to two different positions to accommodate your growing child. The booster back features an integrated shoulder-belt positioning guide, and when your child is ready for the backless configuration, there is a belt-positioning clip that keeps your vehicle shoulder belt at the correct height for maximum safety. The contoured seat is comfortable for long rides, and the cushioned seat cover is machine-washable for easy cleaning. The Batman High-Back Booster Seat comes with a cup holder that is easy to attach on either side for easy access to a drink, snack, or toy. It measures 17-1/4 by 14-1/2 by 25-1/2 inches (L x W x H) (headrest down) to 17-1/4 by 14-1/2 by 28 inches (L x W x H) (headrest up), and it weighs 12 pounds.
