The AFFIX? Highback Booster with Latch System helps safely transport your "big kid" from 30 to 100lbs and up to 57 inches tall. This seat provides a secure connection to your vehicle seat with its unique one-hand front-adjust latch system. With one hand, you can create a secure connection using your vehicle's anchors to keep the booster steadily in place. The connection secures the booster seat to your vehicle seat and makes self-buckling easier for your independent child. The seat has an integrated cup holder and hide-away storage compartment to keep child's drinks and favorite things within arm's reach. Parents love that it secures the booster to their vehicle seat and aides in their child's growing independence.
