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.

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.

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 product!
I babysit my grandchildren. It was time to switch from a regular carseat to a booster. After reading some reviews I decided to purchase this one. It’s a hit will my granddaughter. She likes the colors. She says it’s comfortable. It seems to be made nicely. It doesn’t take up a lot of room, so I can remove it easily when not in use. It was a great value. When it’s time to replace the next one I will be ordering another one.

Inexpensive, light-weight booster
I bought this inexpensive booster seat to have an extra for when we transport our child’s friends for short trips around town. It serves its purpose well. It’s light-weight and not too thick. Our daughter says it’s comfortable when she has used it. Price is right, especially now that it’s on sale!

My kid complained about a sore bum after 2hrs drive. So.. in the end it’s not too comfortable..but then again.. how often do you ride 2hrs if you don’t have your own car. Right?Sturdy and looks good.

Me imaginé que era un poco más acolchonada, es algo delgada la cubierta. Llevamos dos semanas utilizandolo y hasta el momento no ha habido quejas de mi niña de que sea incomodo o algo así, comento esto ya que es de plastico duro. El asientito va prácticamente suelto, solo se gancha con el cinturon de seguridad, no se ha resbalado ya que le puse un protector al asiento.
