We travel with two big spoiled rotten (because they're both challenged, one physically one mentally) cats. Took the thin hard mattress out, and it becomes their little sanctuary. There are three deep storage bins in the back we can't reach; cushions in each, and each one has their own little bed, with a spare. Their food and water is up there, too. Really frees up the floor space from cat detritus. Found a cheap cat tree that after some modifications which became a ladder/scratching post for them to get up. They usually just jump down to the couch. They seem to love the high point advantage to see everything going on!
