Graco has been manufacturing the Nautilus 65 LX car seat since 2007, with minor modifications and improvements along the way. The Nautilus 65 LX 3-in-1 provides parents with a 5-point harness car seat, highback booster seat, and backless booster seat all in one. If your child is over 22 lbs then you can invest in this car seat and use it all the way until children are grown.
Graco also makes available a similar Graco Nautilus 65 version that does not have the increased weight limit up to 120 lbs. This increased weight limit lets parents delay the transition to a regular seatbelt and instead leave children buckled safely into the car seat longer. Parents won’t find much difference in the design of the two seats, and the difference in price is usually fairly negligible.
