Not very up on Scratching posts but I do know that my cat wouldn't use a small one and continued to scratch my sofa but will use a larger stronger one, we bought one from PAH. I placed it initially by the side of the sofa she was scratching with some catnip toys on it and encouraged her to use it, gradually I moved it from the sofa to the back of the room and she's never purposely scratched the sofa since.
