I ordered the 9x7 I think... I put it over my other rug because it seemd kind of thin, its not quite as big as my other 9x7 and it wrinkles a lot which is annoying. Also the smell kind of creeped me out, like I am creating my own indoor air pollution. My cats smell like it after the lay on it, which I also don't love. Also I've been finding a few tufts of it coming out.
