I have it under my rolling chair in front of my computer desk so I am able to move so much easier to reach needed items around me on my carpeted area. It is great and just the right size and cleans up so quickly. If I drop anything I still can see what I dropped because it has not discolored .
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.
