Excellent just as described. Use at work on carpet - you would not be able to use this mat on hard floors - it has spikes on the underside to grip the carpet. mat is thick and durable. only dislike are the spikes they are sharp its large so it was hard to get into place but now that its there love it!
The carpet pads were rolled up loosely and I did not notice the sticker that said it is intended for use on unpadded carpet. When I got home I left the pads in my garage until the next day and when I attempted to unroll them they had become wrinkled and misshappened by the heat in my garage. After leaving them in the sunlight they were OK and I saw the sticker. Bad choice on my part because my carpet is padded.
