Its a good size. It stays well on the carpet. The only problem is that it’s not thick and hard enough. The wheels of my chair make dents and it’s hard for me to come out of the holes to roll my chair back and forth. Other than that it’s ok.
The size is good - but it moves around too much. Had to put weights on it to keep it from moving. It should have been a high pile carpet protector - thought that's what I bought.
the chair mat was a replacement for a previously purchased staples mat. I thought it was identical to the old one but it seems to be slightly thinner than the old one. I am concerned that it might wear out sooner. we'll see how it performs.
