It's great at first. But within a couple uses the chair wheels make dents in the plastic and you can't remove them or change position. The mat determines where the chair is. Then it's difficult to roll chair without effort.

We apologize that your chair mat is damaged. If you would like to give us a call at 800-425-0049 our Staples Brand Group would be able to help you.
I appreciate your taking care when the first delivery never happened (or happened somewhere else). I could not move chair on carpet now I can. Product is exactly what it claims to be. Thank you!
