I hadn't heard that term in years, DR Jrand70.
DAVENPORT
It's what I grew up saying. I just looked it up, and it figured largely in the Midwest so that makes total sense. For us, that thing in the living room was always a "davenport", and I think "couch" was the informal word for it. I didn't much hear the word "sofa", or at least begin using it myself, till much later.
So what do I (we) use nowadays? "Couch", mostly, whether or not we're sitting on one like so much fish. When we don't say "couch", it's "sofa". (As opposed to "sofa so far so" as they might say in Trouble in Tahiti. Ratty boo, and all that. If you catch my drift.)
