The Graco Nautilus 3-in-1 Car Seat is a model that can only be used forward-facing.

It starts off as a harness booster for use forward facing from 20 to 65 pounds. The harness can then be removed to convert the seat into a belt-positioning booster suitable for use in the weight range of 30 to 100 pounds.

When a child is old enough, the seat can further be converted into a backless booster seating a child between 40 and 100 pounds in weight.

The Nautilus has been built using a steel frame for strength and durability and is generously upholstered with EPS energy absorbing foam for maximum energy absorption in a crash.

It also has armrests and an adjustable headrest that can be reclined in 3 different positions for maximum comfort. A cup holder and snack storage space is built in.
