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.
The mat still gets dimples from my chair and still slides on the carpet even with carpet tape applied around the edges. It is fine but for the price and the advertising I shouldn't have either problem.
