I needed a larger mat to cover the large area for my chair to be used with my corner desks arrangement. This is the largest I could find that would work which was a plus. However the mat I previously used for my high pile carpet was thicker and did not deform under the chair wheels as the Staple mat does. The Staple mat is OK but I would have paid more for a thicker mat. I felt it would work simarly since it was advertised for high pile as my previous mat was also. The old mat was thicker!
I bought this for my home office. In the store it was my only option even though the display indicated there are several grades to choose from based on one's needs. It works fine not worth a return and continued shopping but it's not what I'd call heavy duty. I'm 130 lbs and there are indentions in it from me sitting in the chair a few hours a day. So far those indents have not obstructed it's ability to be useful.
I ordered this mat from staples to replace one I had gotten from them about 2 years ago. I was expecting a similar product as it was the same price as the previous one I ordered. I was very disapointed when this arrived to find that is was the not much thicker than a plastic runner you would use in a hallway. I would not order one of these agai.
