same here, I haven't had to do any training at all.
I also would try Soft Paws.
You can't stop them from scratching, but you can redirect it. Cats will have different preferences for types of scratching surfaces (cardboard, sisel, vertical/horizontal, etc.). Chloe has a horizontal cardboard scratcher but never uses it (it's the center of the Turbo Scratcher). I have a flat sisel scratcher (it's a nice one made by TrendyCat) that I have been setting on its side so it's vertical. She loves it vertical and ever since I bought it she's been using that instead of my chair. She uses it horizontally too. I hate the way that most cat furniture looks but Target actually has a decent loooking scratching post (though it is pretty short). I haven't had to do much training with her because once I bought the scratching things, that's all she uses.
To train your cat, buy an appropriate thing for them to scratch on and play with them around it and put catnip on it so it's more attractive. When you catch them scratching furniture or something they aren't supposed to, just pick them up and set them on the post. They'll get the hint eventually.
