Cosco booster seat.
Very sturdy, comfortable for the child, easy to use and switch from car to car. We have 2. No cup holder which we don't really need one.

Great for interrmittant use
I use occassionaly in my Uber. Its light weight doesn't take up much space in my trunk. If I have to move it to make more room for luggage I can easily pop it into the front passenger foot well until I drop my passengers off. It is inexpensive and does the job to comply with my state law that requires children under the age of 8 to be in a child seat. The child is also more comfortable.

Perfect Booster Seat for Everyday and Long Trips
We are really happy with this backless booster seat. From the start, it felt sturdy and well-made, which gave us peace of mind. Our child finds it very comfortable, even on longer car rides, and the design makes it so easy for them to buckle themselves in without help. That’s been a huge convenience for us as parents. We recently took it on a long road trip, and it proved itself even more. After hours in the car, our child stayed comfortable, and when we had a few spills and crumbs (as always happens with kids), it was surprisingly easy to clean. Everything wiped right off, and the seat looked good as new. The booster is lightweight enough to move between cars quickly but still feels solid once it’s in place. Overall, it’s safe, reliable, and parent-friendly, and our child genuinely likes it. I’d recommend it to anyone looking for a no-fuss, dependable booster seat for everyday use and longer trips alike.

Great booster seat, but could be softer
The seat is comfortable and lightweight — my child likes it, and it’s easy to move from one car to another. The fabric feels nice to the touch, doesn’t slip, and looks neat. The seat belt fits correctly, and my child sits securely. The only downside is that I wish the seat had a bit more cushioning, especially for longer trips.

Good
We have 2 of them, the kids are happy with the seats. I sometimes have a 6 year old in my car whom doesn’t use a booster seat in anyone else’s car but when in my car she likes using the booster seat! It’s a little extra safety win. Fits perfect next to my daughter’s car seat.

Good for the money
Great for what we needed it for! Quick trip to Florida and didn’t want to carry ours through airports. Pretty light weight and I’ll probably bring home with us
