Graco Baby Nautilus SnugLock LX 3-in-1 Harness Booster Car Seat

Graco Baby Nautilus Snug LX 3-in-1 Convertible Car Seat Harness Booster

Click! That’s the sound of a secure install. The Graco Nautilus SnugLock LX is equipped with SnugLock 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 lb), to a high back booster (40-100 lb) and to a backless booster (40-100 lb) to a low profile 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 belt-positioning booster mode. You’ll appreciate the ease of the fuss-free harness for easy in and out 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.
