Product will not hold up under heavy use. OK for light use or light people. Standard chair wheels with two disks at each of five support points on plush carpeting will create permanent indentations over time. Premium chair mats are available up to 200 mil thickness. I exchanged for a bamboo mat which looks and rolls great.
The casters on our desk chair leave deep indentations in this chair-mat. Similar products we've used have not done this and have felt more substantial.
