I bought this chair mat for my office and it's a bit thinner than expected. When my chair rolls on it it dents in. I'm wondering how long it's going to last if each time I move the mat is flexing into the rug.
The mat slips on the carpet and when I get up from my chair I have to push it back into place. It doesn't crack like others that have the plastic 'spikes' on the bottom so in that regard it's an improvement over that kind.
