Britax Grow With You ClickTight Harness-2-Booster Car Seat
The Britax Grow With You ClickTight Harness-2-Booster Car Seat is designed to grow with your child from forward-facing harness use into belt-positioning booster mode. It supports children from 25–65 lbs in harness mode and from 40–120 lbs in booster mode.
ClickTight installation helps simplify vehicle setup, while a high-strength steel frame, SafeCell technology, V-shaped tether and two layers of side-impact protection help manage crash forces. A 9-position quick-adjust harness and headrest, two recline positions and comfort-focused padding make the seat practical for everyday family use.
Harness-to-Booster Design for Growing Kids
The Grow With You ClickTight begins as a forward-facing harnessed car seat and later transitions into a belt-positioning booster as your child grows. This extended-use design helps families keep one seat through multiple stages of forward-facing travel.
