It converts from a rear-facing infant seat to a forward-facing 5-point harness seat and a high-back belt-positioning booster. ClickTight is as easy as buckling a seat belt, so you can install with confidence, every time. A high strength steel frame, crumple zone, and V-shaped tether help absorb crash energy. And, 2 layers of side impact protection surround your child’s head, neck and torso.
