CLICK. That’s the sound of a secure install. The Nautilus Snug Lock LX is equipped with Snug Lock Technology for a hassle-free installation 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 lbs.), to a high back booster (40-100 lbs.) to a backless booster (40-100 lbs.) to a slimmer backless booster (40-120 lbs.). 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 Snug Lock LX grows with your child and is the last car seat you’ll ever buy.
