I am looking into replacing my dining room table as well, and as I have started to design the new one, I realize that what I want to do is redesign my sette so that it is U-shaped, with a very small table that will expand twice in two directions: Twice toward the starboard, and twice toward the port. Each direction would have a second fold down leave that would bring the table out further so that six could dine. Two would sit on the port sette and four would sit in the original seating position in the dinette. In this configuration, the seat that was added to make the U would not be available, but if you fold up the starboard leave, then you could sit in the seat added for the U, but the table would be smaller. I will eventually diagram this out and make it available. Has anyone built anything like this before?
