Grow With You™ ClickTight by Britax grows with your child from toddler to big kid. The seat is tailor-made with a 4-way stretch athleisure fabric that’s comfy and easy to keep clean. Install confidently, every time. With ClickTight, you know it’s right in 3 easy steps. Open the seat, thread & buckle the seatbelt, and click it closed. Once your child is ready to use the seat belt, the 5-point harness tucks away, transitioning to a belt-positioning booster. Colour-coded guides help you and your child route the seat belt through the right paths.
