Choose a toddler car seat that grows with your child from toddler to big kid age with the Britax Grow With You ClickTight harness-2-booster car seat. This high back booster seat starts as a 5-point harness car seat and converts into a belt-positioning booster that works with your car's seat belt. With ClickTight Technology, you can install with confidence, every time in 3 easy steps: open, buckle and close. Quickly adjust the 9-position harness and 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 the seat to a belt-positioning booster. The color-coded belt guides help you and your child route the seat belt through the right paths for a secure fit. This forward facing car seat is made with naturally flame retardant fabric and foam that is safe to machine wash and dry. SafeCell Technology in the base acts as a crumple zone to help absorb crash energy for additional protection for your growing child. The protective seat shell and foam-lined headrest help absorb impact energy and are designed to help keep your child's head, neck, and body safe. This booster car seat features armrests, 2 cup holders and harness comfort pads, so even big kids enjoy the ride.
