We already have one chair mat that has worked great but need a second one. We bought this without much research and unfortunately it moves slowly across the carpet and the wheels on the chair leave indentations in the plastic. I needed to buy a sturdier one that had spikes to hang onto the carpet.
The Staples Carpet Berbercmat Chair Mat I recently bought and was asked to review is a total disappointment. It is a chair mat and it looks and a like a chair mat. That's where the good news ends. At 180 lbs I don't consider myself inordinately heavy. This mat is on tight Berber carpeting and the mat is so soft the wheels and on my chair sink into the "plastic" (or whatever the Berber mat is made of) making it difficult for me to roll my chair around on it. This happens after sitting for minutes not hours. I have a bad back and don't want my chair to "stick" to my chair mat. That's exactly what this mat does the wheels compress the mat which keeps them from rolling causing my whole body to be stopped when I try to move and that's painful. 😣 It may be a great mat for a solid floor. ANYTHING with ANY give to it will make the chair "stick" unless you weigh a lot less (no clue how much 150 130 110 ... ?). 👎
