I am trying to identify a couch that my parents owned. It was a bench style hide a bed sofa. This couch was from the sixties and had storage space under the seat for blankets and pillows. The seat could be pulled out on rollers and then pulled up and pushed forward to release the back of the couch so it would convert and lay down for sleeping. There were NO removable cushions. Some have identified it as a Klappcouch, which I have had no luck searching for. Can anyone give me a better name that I can search with or know where I can locate such an item?
