The mat is completely unsatisfactory. It came tightly rolled in a box. It was very difficult getting unrolled to be able to lay on the floor and even now the edges are still raised and are a tripping hazard. Otherwise it does the job rolling the chair on the carpeting.
Unless your carpet is very thin (or old) this mat is too flimsy to work. The wheels of the desk chair make deep indentations and it becomes impossible to roll across the mat. Unfortunately it will need to be returned.
Chair mat blends nicely with carpet…but after two weeks in place it already has indent marks from the wheels on the chair bottom…can’t help but to wonder about longevity.
Chair sinks into mat after awhile so you have to try to roll past the divot created. (I am not that heavy). The mat does scoot around on the carpet though most every mat I have had does so. Otherwise the mat works okay.
