This rug pad was not unlike Teflon. It took a rug that was somewhat prone to shift slightly, to a rug that slipped and slid all over the place.  With this pad in place, the rug also bunched up and “flipped”.  Don’t buy this pad.  It does the exact opposite of what it is supposed to do.  The pad lasted about an hour in my office, and then I tossed it in the trash.
