The dining area in my new home is small 9' x 9' (but can extend into the living room a few feet.) I have an extendable dining table that can be 47" or 65" or 83" long depending on whether the leaves are used. To maximize space, I want to use a banquette or bench against the wall on one of the long sides of the table. What size should I get? Should I base my choice on the length when closed or the length when partially or fully extended? I expect the table to be closed most of the time, and extended when I have guests. If I go with a two seater bench, will it look funny to pul a chair alongside it when the table if fully open?
