Heck, we also say "depot". The USA is so large and has so many cultural areas, that 'almost' any usage can be found somewhere, and those who have traveled widely will have heard it, even if we don't use it.

I recognize 'sofa', 'divan', 'couch', 'settee', and even 'lounge' in some contexts, though couch is what I'd likely say first. (Yes, I realize that each has some more specific historical referent.)
