Title: Mod Black

Grow With You™ harness-2-booster grows with your child from toddler to big kid. Safe to machine wash & 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 & 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. Choose from plenty of fun colors to match your child’s unique personality.
