Sofa wall beds

A sofa bed comprising:

• a carcass having first and second sidewalls and top and bottom panels, the carcass providing an inside and an outside, and also providing an interface between the inside and the outside;
• a bed base, rotatable to lie coplanar with the interface when the bed is in the closed position and at a right angle to the interface coplanar with a floor when the bed is in an open position;
• a sofa base and a sofa back disposed to enable a person to sit thereon when the bed is in a closed position and foldable against one another beneath the bed base when the bed is in an open position;
• where the bed base comprises an armrest for a seated person to rest their arm when the bed is in a closed position and where the armrest acts as a proximal bed support at the end of the bed base closest to the carcass when the bed is in the open position;
• where the sofa bed comprises a distal bed support for the bed base at the end of the bed base furthest from the carcass, the distal bed support being transformable to a support function as the bed base is moved to an open position;
• where the sofa bed comprises a gas strut fixable at a first end to the armrest and at a second end to the floor, the gas strut lying outside of the carcass, such that the gas strut is uncompressed when the bed is in the closed position and compressed when the bed is in the open position;
• where the bed base comprises at least one of:
• a shelf, rotatable under gravity relative to the bed base when the bed is moved to an open position to act as said distal bed support;
• and
• a sofa base, movable from its position as a component of the sofa as the bed is lowered into the open position to position where the sofa base is operable to act as said distal bed support.
