I guess it's ok for the money but I've had better very thin and chair wheels make deep grooves and get stuck won't be long before it rips ok maybe on hard floor but not good on carpet
Not suitable for many residential carpets or medium or thicker commercial carpets. 2" double-wheel castors dent the surface. That's fine if you don't want your chair to roll around. (??)
I've been using this desk chair mat for 2 weeks on medium pile carpet. My 5-wheel desk chair does leave divots while I'm working/sitting in the chair. So far the divots are not persistent; they level out in a few hours. I have not found the divots to be a significant issue as others have commented. If you want no divots using a desk chair mat on medium pile carpet one option is to spend 5x on a glass chair mat. For the price I think this vinyl mat works well.
