CLICK! That’s the sound of a secure install. The Nautilus SnugLock LX Harness Booster is equipped with SnugLock Technology for a hassle-free, 3-step installation in less than one minute using either vehicle seat belt or LATCH. In three easy steps, you can feel confident you've got a secure install. The 3-in-1 harness booster converts from a 5-point harness booster (22-65 lb) to a highback booster (40-100 lb) to a backless booster (40-100 lb) to a slimmer backless booster (40-120 lb). The Simply Safe Adjust Harness allows you to adjust the harness and headrest together as your child grows, and then the harness stores away easily in booster mode. You’ll appreciate the ease of the fuss-free harness and machine-washable fabrics. Little passengers will enjoy the dual cup holders, armrest storage, and recline. Nautilus SnugLock LX grows with your child and is the last car seat you'll ever buy.
