The product is a bit small for my needs and retains wheel indentations making it hard to roll my chair. Will most likely return it and find a different product.
I have never paid so much for something so filty dirty. Had to lay in grass outside & wash off 3 time before could bring in my house.!!! It was like pencil lead powder all over it ! Once clean -- It was just what I wanted.
When I first saw the mat the quality and heavy thickness seemed perfect to use on my plush 1" pile carpet. But after one use I discovered that the mat is not sturdy enough to prevent my office chair wheels from sinking into the mat when I'm sitting down. This renders my chair completely stuck in plastic sink holes so my chair will not roll on its wheels. Bummer. In general however I would say that the mat would be a very nice quality mat for low to medium pile carpets but not high pile.
We have it on thick carpet and it is too soft the edge curl up when you roll near an edge. Also the teeth aren't large enough to bite into the carpet so it slides around.
