This just came in from Richard and barely needs explaining, though we've never seen anything like it: The Doc XL. It is exactly what it looks like, and blows the doors off of a regular old sofabed (though ain't great for snuggling couples)...
The Doc XL is a sofa that fiips up into a bunkbed and requires "a simple gesture and no physical strain." You don't even have to take the sheets off of the beds before restoring it to sofa config. It is available through that august outfit, Bonbon Trading, from the UK.
