The chair mat is just what we needed to replace one that was 11 years old. Also it was at a fare price. I am sitting in a chair in that is on the mat in front of our computer. A smart purchase.
Didn't even rate the one star I gave it. This is not strong enough to roll a chair on. There are depressions in it after sitting on the chair for a while. Do not recommend this product.
It is too flexible. Wheels of chair sink into it and the chair does not move smoothly over the surface. Chair will not roll well at all. Mats I have had in the past were hard plastic and the chair wheels could move smoothly without sinking into the mat.
