First it was difficult to unfold and place where it was needed. Second it is difficult to roll my chair (or any chair for that matter as I tried 3 different chairs) on it to get a comfortable seat in front of my desk. I hate this product!
The chair mat for a carpeted surface looks great but the wheels of my office chair sink into it making initial movement difficult (and annoying). The mat I replaced did not have this problem and yes the carpet is the same.
