Graco Nautilus- 5 years old, 42 lbs, 43 inches

The Graco Nautilus functions as a 5 point harness, high back booster, and backless booster. It is an excellent option for children that have outgrown their rear facing convertible car seat and are at least two years old. Ideally, children should ride rear facing until 3-4 years old before moving to a seat like the Nautilus. With a 65 lb weight limit on the harness and an 18″ top harness position, it will easily last most children until they are ready to move to a belt positioning booster (typically around 5-6 years old). The seat easily transitions to booster mode by removing the harness. The Nautilus positioned the seat belt properly on our 5-year-old tester in both high back and backless mode.

Graco Nautilus recline function

 

 

 

The two drawbacks of the Nautilus that commonly draw complaint are the position of the crotch buckle and the lack of head support for sleeping. The crotch buckle has two positions: 5.5″ deep and 7″ deep and the strap is 4″ long. This can be uncomfortable for older, bigger kids at the upper end of the harness limits.

There is a recline option on the seat, but it mostly serves to help with achieving a solid installation — the recline foot does not typically make much difference in the child’s overall comfort or help keep the child’s head upright when sleeping in the Nautilus.

The lack of head support for a sleeping child is a drawback to the Nautilus. The seat’s design often creates “head slump,” where the child’s head falls forward while asleep. This does not pose a safety concern, but can be a comfort concern for some children.

One important detail to note when threading the harness between positions is that the harness straps MUST go over the red rollers, as shown. Remember, forward facing harness straps should always be positioned at or above the child’s shoulders.

 You can find the Graco Nautilus on Amazon.com, usually for under $150, making it a great value. Neither Graco nor Amazon sponsored this review, opinions, as always, are all our own!
