1 Month update:  I've had this for 1 month now and I dislike it even more. It slides around and the wheels of my chair sink into it because it is not thick enough. I have another mat from a different maker on the same exact carpet in a different room. It costs half as much and is even higher quality than this. I might as well have taken a hundred dollar bill and set it on fire since this is going on the burn pile. Just for the record, I am an ordinary consumer and have no interest in any other company that sells or makes these. This review is based on my experience only.

I bought this because it said it was for high pile. The points on the backside are no longer than the points from a much cheaper alternative. In addition to the sliding problem, it is much too thin and the wheels on my chair seem to sink into the plastic. Not at all what I expected or thought I was buying after reading the description.
