Did not live up to standard. Was replacing one that had "ponded" and then broken up thru the years. Found this one that was the same thickness as the one I had for several years. While the thickness was the same this mat has already permanently indented where the chair wheels sit within the first week. Apparently the durability is not as good as the past mat of the same thickness. It sits on carpet that I would consider low to medium pile. Am going to have to consider adding an additional mat on top of this one
The little bumps are not quite high enough--or my old old carpet is getting longer in it's old age! The mat has a tendency to slowly move out from desk. Buyer needs to be sure the 'medium" is what he/she needs
