The Britax Grow With You Harness-2-Booster Seat grows with your child from toddler to big kid and has loads of convenient features both you and your child will appreciate.
Safe to machine wash and dry, the removable car seat cover stays looking like-new, mile after mile. No more hand washing or waiting for it to air-dry--just 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, so you can be sure that your child is safe and secure!
