This is a decent product for the price. I purchased to use primarily at home. After having a rolling chair and no mat I was determined not to ruin any more carpet. The only con I have is for the shape. Since I have a small desk at home the portion that fits underneath the desk is to short. There is about 11 to 12 inches deep of unprotected carpet. The remainder of the area is just perfect. Great buy!
I chose one of the less expensive floor mats as a beginning point. This one would be fine on low pile carpet with very thin or no padding. I am not heavy and the chair wheels sink into the mat and into the padded carpeting. The good part is the mat is sturdy enough it has not cracked in the 2 1/2 months of ownership.
