I guess you would say this mat is o.k. for the price. The main problem with it is that chai wheels dent it easily making it more difficult to move around on it. I'm not overweight at 157 pounds so I think most people will have this problem.
Despite being intended for medium carpet which I have according to the given depth measurement the chair wheels still create depressions after sitting for a while making it difficult to adjust the position of the chair slightly.
I had a previous mat that started to break down getting holes in it. I knew that there was a Lifetime Warranty on the original purchase. I spoke with the folks at Staples in Mooresville NC and they were awesome in honoring the warranty. Thank You very much!
I have low pile carpet and initially purchased the “Medium Pile Mat”. This mat was too soft so I upgraded to the “High Pile Mat” which works fine… If you are thinking of purchasing one of these mats regardless of your assumed carpet pile height I would recommend purchasing the high pile offering. This way you will be sure to get the stiffest mat available from this manufacturer. I cannot attest to how the High Pile Mat will work with High Pile Carpet.
We love our new chair mat. It was delivered on time and was already laid flat. Usually a mat might be received rolled and then you have to let it lay out for a day or two to flatten-not the case with this.
