Britax Grow With You ClickTight Harness-2-Booster Car Seat


As a harness-2-booster seat, the Britax Grow With You ClickTight Harness-2-Booster Car Seat grows with your child from toddler to their preteen years! With its patented ClickTight Installation, you’ll know it is installed correctly in three easy steps - simply pinch to open, thread and buckle the seat belt, and click it closed. Combining safety and comfort, the Grow With You ClickTight has two layers of side impact protection that surround the head, neck & torso, plus SafeCell Impact Technology to create a crumple zone that absorbs crash energy.

Use the included harness first when your child is between 25 and 65 pounds, and between 34 - 49 inches tall, then transition to the booster mode with seat belt only when your child is between 40 and 120 pounds and 44 - 63 inches tall - Britax strongly recommends that children should be secured with a harness system until they exceed the weight or height limits specified.
