A foldable sofa-bed, comprising: a base with an internal cavity and a rear member, the base configured to rest on an underlying surface; a foldable bed that includes separate and distinct head, intermediate and seat sections (24, 20, 16), each with a respective cushion (25, 21, 19), the seat section also including an underlying seat frame, the intermediate section including an underlying intermediate panel and the head section including an underlying head panel, wherein, in a folded position, the intermediate and seat sections (20, 16) are generally horizontally disposed and positioned in vertically stacked relationship in the internal cavity of the base, with the seat section above the intermediate section, and with the intermediate and seat cushions (21, 19) facing generally upwardly, and the head section is generally vertically disposed and positioned adjacent the rear member of the base, with the cushion of the head section facing forwardly, and in an unfolded position, the head, intermediate and seat sections (24, 20, 16) are generally horizontally disposed and in serial alignment with each other to form a sleeping surface with the cushions (25, 21, 19); and a bed folding mechanism that is attached to the base and the head, intermediate and seat sections (24, 20, 16) that controls the movement of the bed between the folded and unfolded positions; wherein in moving from the folded to the unfolded position, the intermediate section maintains generally the same orientation; and characterised in that the bed folding mechanism further includes a linear power actuator to move the bed between the folded and unfolded positions. a base with an internal cavity and a rear member, the base configured to rest on an underlying surface; a foldable bed that includes separate and distinct head, intermediate and seat sections (24, 20, 16), each with a respective cushion (25, 21, 19), the seat section also including an underlying seat frame, the intermediate section including an underlying intermediate panel and the head section including an underlying head panel, wherein, in a folded position, the intermediate and seat sections (20, 16) are generally horizontally disposed and positioned in vertically stacked relationship in the internal cavity of the base, with the seat section above the intermediate section, and with the intermediate and seat cushions (21, 19) facing generally upwardly, and the head section is generally vertically disposed and positioned adjacent the rear member of the base, with the cushion of the head section facing forwardly, and in an unfolded position, the head, intermediate and seat sections (24, 20, 16) are generally horizontally disposed and in serial alignment with each other to form a sleeping surface with the cushions (25, 21, 19); and a bed folding mechanism that is attached to the base and the head, intermediate and seat sections (24, 20, 16) that controls the movement of the bed between the folded and unfolded positions; wherein in moving from the folded to the unfolded position, the intermediate section maintains generally the same orientation; and characterised in that the bed folding mechanism further includes a linear power actuator to move the bed between the folded and unfolded positions.
