Grow With You ClickTight grows with your child from toddler to big kid. The Cool N Dry mesh fabric improves air flow for a cooler ride. Made with 30% bamboo charcoal, it wicks away moisture to help keep your child dry. 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. 2 layers of Side Impact Protection surround the head, neck & torso. SafeCell Technology in the base acts as a crumple zone to help absorb crash energy. 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 and your child route the seat belt through the right paths. With easy-to-clean arm rests, 2 cup holders, and snack storage, even big kids enjoy the ride.
