Grow with you ClickTight grows with your child from toddler to big kid. The cool flow mesh fabric improves airflow to keep them cool and comfortable. In addition, the seat and headrest are padded for nap-friendly rides. 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 include an energy-absorbing shell and foam-lined headrest that surround the head, neck & torso. Safe cell impact protection in the base creates a crumple zone that absorbs crash energy to help keep it away from your child. Quickly adjust the 9-position harness & headrest using just one hand for the proper fit as your child grows. Once your child is ready to use the seat belt, the 5-point harness tucks away, transitioning to a belt- positioning booster. With easy-to-clean armrests, cup holders, and snack storage, even big kids enjoy the ride.
