I consider my office carpet to be low pile but the chairmat is soft enough that the wheels sink into it. This is probably the case for any chairmat at this price point.
The overall feel & integrity of the chair mat is good but it "indents" wherever the chairs rests and is harder to roll. Otherwise it remains flat which is what I was looking for. The previous one i purchased was thinner and did not indent but it lifted & was a tripping hazard. This is NOT a tripping hazard.
