Looking for Foam Foldout Couch

Does anyone know where I can find the type of foldout couch that is made of foam. I just saw a new trailer made by Jayco that had a couch that had thick high density foam panels (6" to 8"). It was not a jack knife type, or a hide-a-bed type set-up, but kind of rolled out. The bottom was rolled out toward the front, then it unfolded a second time to made it almost 80"s from head ,to the foot, of the bed. It was really comfortable. I found that type of bed on the Lippert web site. They stated that they were only available thru their dealer network. They call theirs the Tri-fold Sofa. Is there an additional brand available? Is there a direct source? LC
