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

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.

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!

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.

Great car seat for when my toddler outgrew the rotating seat. Easy to install and comfortable

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

Comfy for the kiddos
Got this for our boy and he loved this seat. It was comfortable for him and he didn’t complain about the straps like he did on his old car seat. Was easy to install and easy for him to get in and out. Would recommend!

Very disappointed with this purchase. The car seat was sold as new, but the box arrived badly damaged with a large tear in the side. When I opened the box, I found a loose Oreo cookie at the bottom of the packaging. There was also very little protective packaging inside the box. While the car seat itself appeared to be in good condition, finding food debris inside the box made me question whether the item had been opened, returned, or mishandled before it reached me. For a child safety product, I expect much better quality control and packaging. This experience left me uncomfortable using the seat and I will be returning it.

Cheap, light car seat.
Could not get a tight install in 2022 Ford Expedition due to seat belt style/webbing. Chatted with both local CPST and the Graco customer support. Support was helpful but I still did not trust the install. It felt very loose and cheap. Seat is aesthetically pleasing, but the quality is lacking. It also didn’t seem comfortable for longer trips. Returned product sadly.
