US Patent 10376073 Rolling foldout cabinet bed

A foldout cabinet bed has two faces that fold out from a vertical position to a horizontal position, thereby creating a surface that can be used for sleeping. Each face has two side rails for enclosing an area for placing a mattress. The rails are dimensionally asymmetrical such that one of the faces has a smaller rail height/depth than the adjacent rail on the other face. The shorter rail height is smaller than the thickness of the mattress, thus allowing a user to comfortably sit on the edge of the mattress. The taller rail height is larger than the thickness of the mattress and provides a headboard.
