The mat overall is OK - but should have spent a few dollars more for one a bit thicker. This one is a tad flimsy and have found that the corners stick up a little on the outer edge with chair on the mat.
The mat is over what I would consider an average home carpet pile. After sitting in my 5 wheel office chair for a few minutes the wheels sink in. It is difficult to roll. The mat is too flexible or soft for home carpet
