This product is a little disappointing. It doesn't grip my carpet at all, which makes it move about and them start to bend up at the edges and go out of shape. I have tried to hold it down by placing it under the legs of my desk, but it still keeps inching it's way forward and I then have to try to pull it back. I think it may work a little better on a very thin carpet, as my office chair wheels have made their own deep indents into the plastic and it won't move as easily as it first did. That said it has protected my carpet which does have a fairly deep pile.
