I use this projuct as a chair mat. There is not a lot I could say about any chair mad. The one thing I could say is that it was a lot easier to move around than the one it replaced
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.
I was so desperate to have a new floor mat but i did not want the sixty dollar mats but I also did not want to purchase the elcheapo ones either. So my husband and I chose two of these and we love them.
