The coach in the salon area of my 1990 39 Sea Ray Express is supposed to make into a bed. Are there any archive records that will show how this is done or list the parts needed. All that is in the bag for converting the couch into a bed are two long cushions that make up for the length of the couch and a half moon piece to fill in the small circular area. Along with three short poles that are supposed to fit into the long cushions. The backs of the couch do not come apart they are part of the boat.
