I had a bought a new 5 x 7 carpet from Wayfair but it had a meshed bottom.  I knew I needed a rug pad as I have hardwood floors and each time my fur-babies decided to run after each other, (they are siblings), my rug ended up everywhere than in place.  I went back to Wayfair, found this rug which fit perfectly under my woven rug and no more kitties using it for a sliding ride!!!  I would order one like this again because it can be cut to size and I have to buy another rug for my bedroom so I will order another of these rug pads for back up.  You go Wayfair.  BTW, havent heard your jingle lately.   )
