Britax Grow With You – Mod Black

Grow With You harness-2-booster grows with your child from toddler to big kid. It is made with premium fabrics and padding for superior comfort and style. 2 layers of side impact protection include an energy-absorbing shell and foam-lined headrest that surround the head, neck and torso. SafeCell Technology in the base acts as a crumple zone, helping to absorb crash energy and keep it away from your little one. Quickly adjust the 9-position harness & headrest using just one hand for the proper fit as your child grows. When they are ready to use a seat belt, the 5-point harness tucks away, transitioning to a belt-positioning booster. Colour-coded guides help you and your child route the belt through the correct paths. Installing the seat is simple using the premium, quick-push LATCH connectors. And, with armrests, cup holders, and harness comfort pads, even big kids enjoy the ride.
