There are no cup holders included. It’s just the seat with spaces for the cup holders.

Great for price!
[This review was collected as part of a promotion.] Great option for our four year old. Only complaint is that the straps sometimes get twisted making it more difficult to buckle when it happens.

Perfect for a tall toddler
[This review was collected as part of a promotion.] This is the perfect car seat for my tall 3.5yr old toddler that wears 5-6yr old clothes. It is a very comfy seat that doesn't take much space and makes her feel like if she was seating on the actual backseat of the car.

Expect better from Graco
There is no padding for the seat. Just a thin cover over hard plastic. I would never expect a child to sit in this for any length of time.

Perfectly adequate
[This review was collected as part of a promotion.] It goes in the car very easily and it's relatively cheap for a car seat. However, it is very hard to clean. My daughter vomited in the car and cleaning this thing was a struggle. My other Graco (the 360) is a lot easier and allows me to pull the cloth parts off to wash, without removing straps. On this Graco, you have to remove the straps to get all the covers off.

This is the second one that I have bought, not because there was anything wrong with the other one, but because my family is growing and I needed another one. I am very pleased with this car seat, the ease of installing it and removing it if needed. Sturdy, safe car seat, in my opinion!

Best convertible harness/booster
[This review was collected as part of a promotion.] I have now purchased 4 of these for all 4 of my kids. The first one I bought is still in great condition, but we now have 2 in each of our family's cars. Easy to assemble and use daily, lightweight. Flexible. Great purchase, worth the money but is very reasonably priced!

Very nice car for a 4 year old
[This review was collected as part of a promotion.] We are loving our new car seat. My daughter sits comfortably in it and actually falls asleep in it. Her last one she would never. It was easy to install and it’s easy to use. Lightweight and doesn’t take up a ton of space either. Plus we love the color!

Worst Booster Seat Experience – Not Safe
To anyone considering this booster seat: this is the worst booster seat I have ever used. It feels unsafe because it moves around, and the upper seat latch keeps getting stuck. Every time I need to unbuckle my daughter, I have to get out of the car to release it. My biggest concern is that if there were ever an emergency, my daughter might not be able to get out quickly. Unfortunately, I couldn’t return it or exchange it. This is definitely a manufacturing defect. I would not recommend this booster seat to anyone.

Comfy, cute and easy to install
[This review was collected as part of a promotion.] Cute, adaptable and the best part is that it grows with my toddler. Carseats are too expensive these days.

Love this seat.
[This review was collected as part of a promotion.] We have the 10 in one car seat which is great. However for our daughters long legs we ordered this which seemed more comfortable for her. It is. We are still keeping the 10 in one to have for backup. We love them both.

Eh
The seat is very easy to install but the headrest rattles constantly. It makes driving anywhere almost unbearable. The harness straps get twisted very easily and it’s so difficult to fix. It’s slim and great for small cars but the little things become annoying after a few months.

We appreciate you taking the time to leave a detailed review. While we’re glad the seat’s size and installation met your needs, we’re disappointed to hear the headrest noise and strap twisting affected your comfort on the road. That kind of distraction can make any drive stressful, and your experience matters to us. Thank you for highlighting these concerns—feedback like yours helps guide future updates and design improvements. We’re here if you need any support or tips that may help reduce the rattling or strap issues. -Graco Team

Love it configured with the seatbelt guides.
I bought this a month ago and used the full harness which was big enough and easy to use (unlike the previous seat I had). Over the weekend converted from the harness to the seatbelt. The belt is so easy to use. He climbs in and it takes me seconds to thread the shoulder strap thru the Graco. Phew.
