Glad you found them. Our new SOB has 2 chairs that have a flip up seat in them, essentially making each side one chair and a bench seat.
Fortunately, ours was ordered with a second set of folding chairs for the dealer's stock, so, we'll have real seats for the little ones. The point being here, there may be a movement going forward by manufacturers to eliminate chairs with the dinette and get by with some alternative method. Keep an eye out if anyone is buying to make sure you know what is included.
