Grow With You™ harness-2-booster car seat grows with your child from toddler to big kid. It’s made with premium fabrics and padding for superior comfort and style. Installing the seat is simple using the premium, quick-push LATCH connectors. 2 layers of side impact protection surround the head, neck & torso. Plus, SafeCell Technology in the base acts as a crumple zone to help absorb crash energy.

Quickly adjust the 9-position harness & headrest using just one hand for the proper fit as your child grows. Once they’re ready to use the seat belt, the 5-point harness tucks away, transitioning to a belt-positioning booster. Color-coded guides help you and your child route the seat belt through the right paths. With arm rests, cup holders and harness comfort pads, even big kids enjoy the ride.
