Don’t waste your money on this. The plastic is thick enough to make you think you’re buying a quality product but too thin and much too soft to be of any use. There is no sturdiness to it at all. The plastic is so soft and thin that the wheels of an office chair make indentations in it if you sit in the chair making it almost impossible for the wheels to roll smoothly without having to raise up off of the chair and manually move it from one side of a desk to the other.
