My cat has a ton of scratching posts/boards. He enjoys and uses them, but also uses the furniture a similar amount. I try placing the scratching posts/boards in front of the corners of furniture to block it, but there are too many unblocked furniture corners. And even in a blocked corner, he will sometimes go around the block and use the couch anyway. I’m at a bit of a loss, tbh, so I tried ordering some stick on carpeting material and we’ll see how it goes.
