Do not buy
I was sent a car seat that was three years past its manufacture date, Graco states it's "out of their control how long products are sitting on their shelf's" . At this price, selling a three year old car seat is insane granted that it's good 6-10 years so that makes the lifeline shorter. On top of that, I have yet to get a refund after returning.

Great for my older kiddo!
Love it! Easy to clean, simple to set up, and works for my 6.5 year old with plenty of room to stay in a high back seat for years to come.

Nice looking, easy to install and use, lightweight
This is a comfortable, sleek, safe high back booster seat for my growing kiddo - we already have 3 other carseats from Graco and this is the best looking one so far. We are moving her from the harness to the seatbelt and this made it so easy. When my younger one is forward facing, we will be happy to use this seat on him too!

Great Seat
I really like this car seat, much lighter and more compact that the front-facing convertible it replaced, and leaves a ton more legroom for my son in my relatively compact car.

Comfortable, safe carseat; needs shoulder straps
I like the car seat and my kids always say how comfy it is but I wish it came with shoulder pads on the straps. After riding in the seat they end up with a line across their neck from the strap. I had to buy pads to go on them so it doesn’t become painful.

It's awesome!
This car seat is perfect! I love how sturdy it is and how compact it is without compromising the safety. The steel frame makes me feel a lot better about my son being safe if anything were to happen. Even with the frame it is not heavy. I like how compact it is because my son can easily get into it and he has tons of room for his feel as well as in the seat. It fits ver...

We love it
I love how heavy duty it feels, but it’s also not too heavy to switch between cars regularly. My daughter loves it because of her big girl seat and we both absolutely love the color.

Great carseat - old inventory
Car seat is fine. But production date is several years old. So if you are thinking of using it for its full recommended life, it is already old.

Would not recommend
I bought this for my grandson and HATE it. The cupholders are constantly falling off. The latch belt buckles are difficult to work with. So sorry I bought it. Usually happy with Graco products, but not this time.

Perfect not bulky
My child loves her new seat it’s slim & comfortable, I went with this car seat because it’s not bulky, it has a metal frame and all around seems like a good seat for children.
