The Britax Grow With You ClickTight Harness-2-Booster Seat seat grows with your child from toddler to big kid. Feel confident with your child's comfort and safety with its patented ClickTight installation.
Safe to machine wash and dry, the removable car seat cover stays looking like new, mile after mile. That means quick, easy cleanup so you can keep moving. The fabrics are naturally flame-retardant, which means there’s no need for added FR chemicals.
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 to a belt-positioning booster. Color-coded guides help you route the seat belt through the right paths, and you can choose from plenty of fun colors to match your child’s unique personality.
With the Grow With You ClickTight Harness-2-Booster seat, your child will be proud of their "big kid" status!
