I bought this pad for our living room; an area with high traffic. (Five people and a dog.) I purchased a rug at the same time. The rug measures 9X12, to avoid having to cut down the pad I ordered it at 8X11. When the pad arrived it was folded up and had some imperfections in the foam. I was concerned about how it would flatten out but it did so with no problem. The pad did measure smaller than the 8X11 I had ordered- about an inch short on each side; which I assume is done so you don't have to trim it which would have been good to know up front. All in all, I'm very happy with our purchase and would absolutely purchase the rug pad again, but in the exact size of our rug.
