Grow With You™ harness-2-booster grows with your child from toddler to big kid. It’s made with premium fabrics and padding for superior comfort and style. 2 layers of side impact protection surrounds the head, neck & torso. Plus, SafeCell Technology in the base creates a crumple zone that absorbs crash energy. Installing the seat is simple using the premium, quick-push LATCH connectors. And, with arm rests, cup holders, and harness comfort pads, even big kids enjoy the ride.
