I use this product at home in a computer room. It has meet my expectations with two exceptions: the mat slides out of position and divots are easily created by the chair.
I noticed that the newer mats replacing this one are thinner yet. The last one started breaking up in the middle. What does this say about the newer thinner ones? Yes the chair has the double rollers that were recommended! I probably would have purchased a thicker mat if one were available.
