A car seat that grows with your child. Offering three recline angles, adjustable crotch strap and headrest, six harness heights and two extra inches of legroom, the grey convertible car seat allows most kids to ride in the safest rear-facing position until they are four years old. Safety features include energy-absorbing foam layers and aluminum honeycomb technology, anti-rebound bar and advanced side-impact protection. Smooth and sophisticated, the grey performance fabric resists water-based stains and bacteria that can cause odors, and the cover is machine washable.
