Britax Grow With You™ ClickTight Harness-2-Booster Car Seat
The Britax Grow With You ClickTight is a forward-facing harness-to-booster car seat designed to accommodate your child from the toddler years through the big-kid stage. It begins as a five-point harness car seat and converts into a high-back belt-positioning booster when your child is ready.
Britax's ClickTight Installation System helps simplify installation, while the steel frame, SafeCell™ technology, V-shaped tether, and two layers of side-impact protection provide added security for everyday travel.
