Find a car seat that grows with your child from toddler to big kid age with the Britax Grow With You(TM) 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. Installing this toddler car seat is simple using the premium, quick-push LATCH connectors. 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 guide helps 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 fabrics and foam that are safe to machine wash and dry. SafeCell(R) Technology in the base acts as a crumple zone 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 features armrests, 2 cup holders and stay-put harness pads, so even big kids enjoy the ride.
