From infants to older children, the KNOX Convertible Car Seat is the solution that keeps pace. Being able to be oriented backwards and forwards, it easily adapts to the growth and positioning needs of children. Packed with intuitive safety features, the KNOX car seat helps you maintain your active lifestyle, even as baby grows. The absorption and recovery properties of the active headrest's specialized foams provide advanced side impact protection that grows with your child. Placed on the sides of the hull and always engaged, the side impact guards absorb and deflect crash forces in the event of a side impact. The strategic placement of EPP foam between the inner and outer shell ensures that collision forces are absorbed by the seat rather than the child.
