A Car Seat that Grows with your Child

It also functions as a backless booster for kids with 40 to 100 pounds and as a high back booster for kids with 30 to 100 pounds.

What makes Graco 3 in 1 car seat a must buy?

Ease of Use

  • The seat grows with your 20 to 100 pounds child by offering three convenient forward facing positions.
  • The five-point harness can be used by children up to 65 pounds and as the child grows, he/she transitions to a high back belt and finally as the child approaches 100 pounds he/she transitions to belt boosting position.
  • The seat is also easy to use thanks to the open-loop belt guides that ensure proper vehicle belt positioning when in belt positioning mode.


The nautilus 3-in-1 car seat is designed to offer comfort to your children as they grow. It features three recline positions and height adjustable headrest that is easy to adjust. You can simply move it with one hand as the other holds your child. The nautilus car seat is also designed to offer comfort for long rides as a result of its well contoured, padded armrest. It also has an integrated storage and cup holder pockets that keep your child’s favorite sacks in an arm’s reach. (Compare with Britax Marathon.)


With this car seat, Graco has continued its commitment to meet and even exceed all US safety standards. The seat has an EPS tested energy absorbing foam that ensures proper energy management in case of a collision. The seat also ensures that your child is secure from side impact collision with the high back belt positioning mode and 5 point harness system.

Quality / Durability
