Graco’s Commitment to Safety

In addition to meeting or exceeding all US safety standards, the Nautilus 3-in-1 car seat has been side impact tested for occupant retention with the built in 5-point harness system and in high back belt positioning booster mode to keep your child secure in a side-impact collision. This car seat features EPS, energy absorbing foam for effective energy management in the event of collision.

The Nautilus has been tested for structural integrity at both high and low temperatures. Because the interior temperature of your vehicle can vary significantly by season, it is important to maintain the structural integrity of the car seat when subjected to these temperature extremes. Its color coded open-loop belt guides also help ensure your vehicle belt is properly routed to secure your child.

3-in-1 Design Grows with Your Child

The Nautilus is designed for children from 20 to 100 pounds, allowing five-point harness use up to 65 pounds. As your child grows, the seat transitions into a highback belt-positioning booster, then finally into a backless belt-positioning booster for a comfortable fit up to 100 pounds.
