This product is literally saving my wood floors from damage by my desk chair. The chair rolls easilly over it's surface and the mat feels good under foot. The size accommodates the rolling area of the chair perfectly. The only thing that I would wish to change about the product would be if it was clear rather than somewhat opaque. I would like to see through to my wood floor beneath. But I do not know if such a mat can be made and still retain the positive features mentioned above if it was clear and not opaque.
