Full width R&R bed from 1977 Riviera Folds in two halves - each half having two hinges and 2 cushions. Not pictured is the cushion that goes over the engine bay and the other two hinges. The box pictured is also available Based in Orpington just off J4 of M25
Never having used a normal bed I'm not sure. It screwed to the floor, each hinge separately, and then to the base and back of the seat cushions. To turn it into a bed you pulled the seat base and then pushed it back to turn it into the seat. Base doesn't lift up when in the seat position so only way to access is to have a hinged kickboard.
ok. and by folds in two halves, do you mean you can have half as seat and half reclined back to bed mode? kind of like split fold rear seats in modern cars? sorry about the quiz!
