I returned this chair mat shortly after bringing it home. It is so thin that the wheels from my desk chair made fairly deep indentations in it almost immediately. That made it difficult to roll the chair around. I expect that it would crack in a short period of time as well from normal use.
This mat spans the edge of a very low pile rug. the covered edge of the rug spans underneath where my feet end up when I'm sitting comfortably at my desk. This mat fixes the obvious problem of the rug edge lifting up from being kicked dragged and wheeled over multiple times a day. It is also versatile enough to "fit" on both the hard wood floor and the low-pile rug.
