All of my 22's have the table fit on the slightly recessed ledge on the inner part of fore and aft seats. My 25 had a single telescoping base. That goes from full height, to the level with the seats position., A special set of cushions were made--one for use of the settler as a single sofa type or bunk and another for just sitting. The sofa / bunk has a back rest velcroed to the cabin side.
