This mat is not thick enough. When sitting in the chair the chair wheels make indentations in the mat that do not return to normal after a period of non use. Buy a thicker chair mat.
great mat. thick enough for the plush carpet in my home office. did not come rolled up. so its nice and flat. this one was a little thicker than standard mat. worth the extra cost.
Staples makes much higher quality chair mats than this one so I'm not sure why it's for sale. It's basically barely a step up from placing a plastic bag on the carpet. A chair can't roll on it and makes indents because it's so soft. I returned this and got a much heavier mat which I'm very happy with.
