Review: 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.
Review: 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.
