The only thing I would change would be the thickness of the mat. My old one was thicker and the chair moved easier on it. I was impressed with the salesgirl and delivery of my mat. I would definitely recommend Staples and their service. I would also recommend the chair mat.
It is a pretty flimsy chair mat for the price. Just putting my desk chair on it and it dimpled before I even sat down in the chair. Needless to say you can’t roll around on it very easily.
Not much better than no mat - needs to be thicker and more rigid. It’s so thin it must be kept flat or it will be bumpy or fold on itself. I would not recommend.
