This mat is good quality and performs well. This mat is medium thickness (mils) and is a very good value for the price. Thanks to Staples for the ability to compare the mil thickness of different mats and free next day delivery.
This chair mat works perfect it is more durable looking than the old one and we had the old one for 6 years. So hoping to get 10 years out of this one.
It is made for very thin carpet. While rolling over with an office chair the mat moves; after it has moves three inches I have to reposition it. The reason it moves: the protruding fingers on the back-side are way too short and not pointed enough to grip into normal carpeting.
