Wont get tight enough
Overall, this seems like a great product, but for some reason, I could not get it to tighten enough and therefore it slides all over my seat. I am a tried and true Graco fan, as this is not my first child. We have always been Graco product supporters, so disappointed in that. So exchanging for the Nautilus 2.0. And for my parents who can’t figure out the “missing” cup holder - place a finger in the hole and lift up. Flip it around and slide it back in and there you go.

Perfect for big/tall toddler
Bought this for my big 4 year old and she loves it! Her other chair the seatbelt at the bottom was pressing against her legs but this one the harness sits higher and is perfect for bigger/tall toddlers.

Would buy again. Love how lightweight and thin it is. Love that it has 2 cup holders as well and transitions all the way to high back booster and regular booster.

Not a fan
My daughter says it isn’t comfortable. The seat cushion is pilling only after 2 months of having the item. Seems low quality compared to my other Graco car seats, especially for the price.

High Quality for Reasonable Price
So far this is a great car seat. Installing with the latch system was very easy when following the manual. The harness works very smoothly, and my daughter says it's comfortable. Using this seat after using a more expensive car seat for years, and honestly I'm shocked at how nice this is for the price.

Does not tighten!!
Don’t buy this car seat! I just spent over 30 mins trying to get the car seat tight in multiple cars and it will not tighten even using a seat belt. It moves well over 3 inches when wiggling it back and forth. Definitely will be returning.

buyer beware, this car seat is not safe
I was really hoping this car seat would work, it has the features I want and the price point is not bad, but this car seat is absolutely not safe. I read the reviews saying it will not tighten down completely, but there were hundreds of reviews loving this car seat, so I was hoping those few saying it will not tighten had possibly experienced user error. I was wrong. I am a seasoned car seat installer and there is no way to tighten this seat down so that there's not more than an inch of movement in any direction. It moves at least 6 or more inches, sliding all over the seat and it would not tighten any further. How did this seat even pass safety inspections? I'm returning it pronto and I'll have to either settle for a more inexpensive seat without the features I want or break the bank on an expensive seat, either option is not great. Graco this seat is a gigantic failure. For the safety of everyone's children, do better.

Booster seat
I bought this for my grandson. It was very easy to install and is snug on the seat. I read reviews saying it slips but this one stays very tight.

Lower anchors will not tighten
Lower anchors will NOT tighten. I fought with this seat for over an hour because I really didn’t want to deal with returning it and getting a new one. I really tried here but after an hour of getting absolutely nowhere, I gave up. Every time I strained myself with pulling and then checking for tightness, the seat still moved a good 4 inches in all directions. I checked all the tips and hacks online too.

Cupholder dilemma
I wish I had known how the cup holders work. I had to write the company to figure out they weren’t missing. But it’s very light and slim! I love the black color.
