The mat is too soft too flexible. When placed on a carpet the wheels of the chair sink into the mat making it a real challenge to move the chair. I would rate it a 3-star product. It does the job but is as much a nuisance as it is an asset.
I like the chair mat I purchased from Staples in that it protects the carpeting my chair with rollers sits on. No more tattered carpet fibers. I will most definitely purchase one for my wood floors. Thank you!!
It was flat when I bought it so that made it very easy to lay on the floor. It has stayed flat and has not curled like previous mats. This is an excellent mat.
