I use the plastic mat under my desk chair in my home office. The mat is not very thick which results in the chair wheels causing dents when I sit still for awhile. When that happens it is difficult to roll out of the dents. Trying to roll out of the dents without getting up from my chair results in the mat sliding on the carpet. This mat might work better on thinner carpet although it does require some nap. Flat carpet (no nap) or no carpet would not be good for this mat. It has teeth and needs to sink into something. I thought that 'plush' meant either heavy duty or for thick carpet. 'Plush' has turned out to be misleading.
Good product but bought it in Broomfield Colorado and paid well over 8% sales tax. Won't ever shop again at the Staples store in Broomfield because of that.
Perfect size for space .. the only drawback was the incredibly strong chemical odor that persisted for a week after delivery. My boss thought there were burning tires in my office.
