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.
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!!
Had to return it. The office chair I got from Staples left divots in the vinyl and you’d get stuck in them making it hard to roll smoothly. Used on flat Berber carpet
