The Nautilus 3-in-1 car seat helps keep your child secure from 20 to 100 pounds. Nautilus is a 3-in-1 car seat that converts from a harnessed booster to a high back belt-positioning booster and finally to a backless belt positioning booster. The harness booster can be used up to 65 pounds, and as your little one continues to grow, the Nautilus does too, transitioning into a Highback belt positioning booster which can be used from 30 to 100 pounds, and finally into a backless belt positioning booster for a comfortable fit from 40 to 100 pounds.

  • Great Car Seat
    Verified Purchase

    Buy this and you'll never need another car seat again! I love the colors, how easy it is to take everything off to wash and how comfortable it is for my daughter. The fact that it turns into a booster seat is just a plus. My favorite one out there!

  • Great find
    Verified Purchase

    Our daughter has enjoyed this seat both for the comfort and the cup holders/storage compartments. It was easy enough to install and has held up well. She feels secure when it is buckled and it does adjust as she grows. We have not tried it in the booster stage yet.

  • Looks very safe
    Verified Purchase

    My daughter is very comfy in this seat. I love the side head wings. The tummy pad is also a great feature. She actually cries when i try to take her out. The seat was manufactured in july of 2013 which was the only negative about this seat. But overall, im very pleased.

  • comfy big girl seat
    Verified Purchase

    Great price, fast delivery, nice car seat. Have this in hubby's car and*** in my car. This seat is half the price of the *** and very comparable. It's pretty easy to install, straps are easy to adjust and padding is cushy. The only advantage of my *** is the click tight system which makes it so easy to install with a seat belt, but if you don't plan on switching between cars a lot that doesn't really matter. Planning on buying another of these nautilus seats for gramma's car because it's so easy to use and well rated on consumer reports.

  • Love the Nautilus seat!
    Verified Purchase

    I love this car seat so much that I bought it for my second daughter. The seat itself is comfortable and accommodating for car rides and I love the cup holder because it is durable and holds drink steadily. Very safe and converts nicely into a high back booster when the time comes.

  • Q:

    "Can this car seat be installed in the rear facing position?"

    • A:

      Hello tiffanyraern, this is a front facing car seat only. Thank you for your inquiry.

  • Q:

    "Is this an older model?"

    • A:

      Hi debbie8592, after reviewing with our support staff we found that this car seat will have the new buckle as it is the newer model. I hope this helps, thanks for shopping with us.

  • Q:

    "Does this car seat have the new buckle on it? I'm only asking cause I know that at one point the buckles were recalled"

    • A:

      Hello awilley1, this would not have the recalled buckle on it. This comes right from the manufacturer. Have a great day!

    • A:

      If it by chance did not have the new buckles, they can be ordered from Graco free of charge and only take about 5-10 minutes to install. We currently own two that had to have the buckles replaced and it was super easy.
