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.
This product has worked well for me so far. The only thing that was unusual was that the mat was not boxed for delivery (it just had a sticker with the shipping info) but in the end it still arrived in new condition.
