Home-made recipes?

I obtained some couches from a friend, and they smell HORRIBLE. They were covered in cat hair and smell like cat pee. I've tried the baking soda paste recipe, some commercial pet odour removal stuff and even Sol-U-mel. Oh, and steam cleaning. I was wondering if there is anything left to try short of re-upholstering them? Thanks for all of your help!
