I removed the cushions and lined the corners and all along the back of my couch with cardboard, then duct-taped it together and to the seat. I didn't tape it to the back of the couch, because the tape will pull away when humans sit on the couch. For the corners, I used actual corners of cardboard boxes, cut down to size so the cardboard doesn't show above the cushions. The cushions hold the un-taped upper edges in place. So far, so good!
