One4Life with Anti Rebound Bar grows with your child for 10 years. It converts from a rear-facing infant seat, to a forward-facing 5-point harness, to a high-back belt-positioning booster. The anti-rebound bar minimizes crash forces by stabilizing the car seat when installed rear-facing. The seat is made with stain-resistant Nanotex technology, wicking fabric and extra padding for a clean, cool, comfortable ride. With ClickTight, you can install with confidence, every time.
