even with a low pile carpet this mat buckles and doesn't stay flat due to the weight of my chair. Not only is the mat now warped and unreturnable it was actually easier to push my chair over the carpet then the mat.
This is all you had to sell me and it's just too thin. I've always bought my mats at Staples but this mat just let's the chair sink into it and then it's just too difficult to move it around. I don't have thick carpeting but I think this mat would only work on indoor/outdoor carpeting. I won't make this mistake again.
