I'm pretty sure I could make something like this...a few old pallets sanded back, a slab of mattress foam and pretty material to sew it up with. invest in some pretty cushions and you have a cheap as chips lounge!!

The stylish Stefano sofa bed completely redefines the functionality of a sofa bed, lending a superbly unique form factor to the classic piece of furniture.
