The no-rethread harness system allows you to adjust the headrest and harness together with one hand, helping maintain a proper fit as your child grows.

Installation is done via LATCH, which is straightforward and secure for most cars. Comfort is enhanced with nine recline positions and machine-washable covers, making it easy to keep clean.
