My cats love them and use them constantly, and they look nice. Im aware these are meant for walls, but Im using them for my couch corners. They are much bigger than I thought theyd be (an observation not a criticism),  the material where they scratch is a thin layer, so Im curious to see how long it takes for my cats to rip through it. Theyre not sturdy at all, but they are heavy enough they may hurt the cat if it tips it over. If your cat gives a good tug it will fall over if its not attached.  Mine have only done It once so far. It does have 2 pieces of material at the top and comes with screws so you can attach it, but Im not super thrilled about screwing that into my couch, so well see how that works out. I got these for a good price, so Im not disappointed.
