Our TC came with a couch option - it's a real couch, not pillows leaned against the wall. The table is a long rectangle that sits parallel with the couch, and can be turned 90 degrees to overhand the center of the couch making a little dinette. We use the table both ways: usually eating, we just sit side-by-side. If we need to face each other (playing cards or something), we turn the table 90 degrees.
The couch folds flat into a bed, which we usually configure to watch movies with the TV set up on the kitchen counter. When we have the dogs with us, our 120lb lab sleep on the couch in 'bed mode'. The couch is surprisingly comfortable.
I'm a TC couch evangelist: my wife refused to buy a TC with a dinette. She has childhood memories of uncomfortable, straight-backed dinettes, sitting bolt-upright looking at the rain outside for hours.
I'm convinced the ONLY reason dinettes are still used is because it's the traditional arrangement that people expect - and people don't like change. There is (IMO) absolutely NOTHING you can do with a dinette that you can't do better/ more comfortably with a couch (unless you seat 4 - 6 people at your dinette - it's just the two of us).
It boggles my mind a bit that there are people who want a couch AND a dinette in a TC, but to each his own.
