The title is a bit tongue in cheek. However I found the vinyl material to be ill-suited for my needs with my low-medium pile carpet. Because it's not a firm material my chair is constantly sinking into the vinyl and becoming stuck in these wheel sized ruts. This makes it no easier to roll than when I was not using the chair mat. I can't recommend this for anyone who isn't using a low-pile carpet material.
Mat is thinner than I thought and sags a little where my chair wheels sit making it a little difficult to move about. Mat is still helpful office desk/chair sits on indoor/outdoor carpet. Will buy a heavier mat when this one needs replacing.
