IT works great and it is large enough that I can roll around to reach different spots on my workstation. It did not come covered only bent in half and laid on my porch so I had to clean it. I would have cleaned it anyway.
I just refinished my hard wood floor and need a mat for my office chair. This mat works great. The clear design also allowed the beautiful floors to be seen.
I bought this even though the reviews were mixed. I placed it over a 3/8 inch pile carpet that is on a concrete floor. It does not develop deep divots under the wheels yet it is a bit more flexible than my former mat which I hope adds to its durability. My chair glides easily and the softer material in the mat seems to make it very quiet. It also stays put. I have yet to need to move it back into position after a few weeks of use. Very nice. Recommended.
