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.

## Questions & Answers

**Q: Does this seat fit with 3 car seats across one seat?**
A: It would really depend on the size car you want to use them in. A compact...I doubt it, mid size...maybe, sedan, or minivan...should be no problem. I think they're about 20" across if you count the width of the arms, not the width across the bottom which is more like 15" or so. We used this one in a jeep grand cherokee along with a full size carseat. There was room for a 12 year old in between but it was tight and not that comfortable for the passenger.

**Q: Does this meet FAA standards?**
A: Hi B. Wilkens, You cannot use a belt positioning booster seat on the air lines as they require a lap and shoulder belt and the airline seats just have a lap belt. If I can answer any other questions, please let me know.

**Q: what is width of the bottom of this car seat?  I see the dimensions listed, but am curious on width of bottom of seat and again at arm rest level. thx**
A: Hi Brian, The actual foot print of the seat is 11 inches wide. The widest point on the actual seat is 14.75 inches wide.  The width of the arm rests is 16 inches. I hope this  helps. If you have any other questions, please let me know.

**Q: Is the cover machine washable?**
A: Hello, and thanks for your interest in the Top Side Booster!  This fabric padding is not machine washable.  The pad will need to be hand washed with warm sudsy water, rinsed clean and air dried.  We cannot suggest using bleach or other harsh cleaners, nor can we suggest dry cleaning.   I do want to clarify for you if the padding is washed/dried in the machine and it becomes damaged, this is not covered under warranty as all machines are different.  That is why we recommend to hand wash/air dry.  This will also be outlined for you in the product manual that comes with the booster in the event that you need to refer to it in the future!  I hope this information is helpful for you.  Please feel free to let us know if you have any other questions.  You are also welcome to contact us via phone 1-800-544-1108 or email crsocial@djgusa.com (Please enter AMAZON in the subject line so we can identify your email quickly).
