Love that it is convertible!

I love that this car seat height is easily converted up and down. I have two granddaughters with a two year age difference. This seat works for both. No hassling with changing out car seats. As a 70 yr old grammy, none of them are easy for me to install. Padding is cushiony and washable. Cup holders are convenient. Shell and straps seem sturdy and safe.

Easy and Safe

[This review was collected as part of a promotion.] This car seat is very easy to install and to use. I love that it has two cup holders that are big enough to fit the Yeti kids water bottle. I am confident that the seat will keep my son safe until he is tall and heavy enough to be in the regular seat.

Perfect seat!

Graco never fails to impress. I babysit my granddaughter during the day, and since her mom doesn't always have time to transfer the car seat to my car, I decided to get one for myself. After researching online for a seat that would fit her well and stay within my budget, I landed on the Graco Nautilus 2.0. It was perfect! I got it delivered within an hour (thanks to Walmart ), and the look of joy on my granddaughter's face made it all worth it. She was thrilled to have her very own seat in grandma's car. Honestly, I think she enjoyed playing with the giant box even more! Assembly was super quick and easy, and I used the latch/tether method to install it.
