A sofa bed traversable between a sofa and bed configurations is disclosed herein. It has a folding mechanism having first and second pairs of link members rotatably attached to a backrest and support members on left and right sides of the back rest. Via the first and second link members, the back rest is transitionable between the sofa configuration and the bed configuration. A seat base is movable up and down at an angle via a sliding mechanism.

A seat convertible to a bed. The seat includes a locking mechanism for fixably maintaining a head panel section of the bed in a generally horizontal orientation when the bed is in the deployed configuration and releasing the head panel section from the deployed configuration by a lifting motion. The locking mechanism is connected to the head panel section and a mid-swinging member. The mid-swinging member pivotally attaches to the head panel section and a stationary mounting arm. The stationary mounting arm is fixably attached to a seat frame.

An articulated back sofa bed has a top pivoted back that is aligned at a downwardly forwardly aligned angle in a sitting position and, when a mattress supporting frame is deployed to a bed position an articulation mechanism displaces the seat back rearwardly, to a downwardly rearwardly aligned angle, thereby providing clearance for deployment of the mattress supporting frame clear of the bottom of the back, thereby allowing for a compact overall footprint for the sofa.

A cushion, mattress or mattress section for a convertible furniture article defines a plurality of apertures, such as slits or slots or recesses, extending into or through the cushion or mattress section that are cut in a direction at an angle to the first length of the mattress section. The cushion or mattress section expands from its first length to a second length that is longer than the first length upon applying a stretching force to the cushion or mattress section and thereby positioning the mattress section into the open or sleeping configuration. Expansion is due to resilience of the material forming the mattress or mattress section in combination with opening of the apertures. The sleeping surface of the mattress or mattress section may remain substantially planar in both the open (sleeping) position and closed (seating) position.

Furniture that is convertible between a seat position and a bed position is described. The furniture includes a first bed section with a first platform supporting a first cushion, and a second bed section with a second platform, a second cushion, and a partition disposed between the second platform and the second cushion. The first platform is configured to pivot relative to the second platform. The first cushion is thicker than the second cushion. When the furniture is in the bed position, a top surface of the first cushion is substantially coplanar with a top surface of the second cushion and the partition is spaced from the second platform by a first distance. In the seat position of the furniture, the distance between the partition and the second platform is less than the first distance.

A sofa bed is configured to be switched between a sofa configuration and a bed configuration. The sofa bed includes a base frame, a middle frame rotatably coupled to the base frame, a seat-and-foot frame rotatably coupled to the middle frame, a back-and-head frame rotatably coupled to the base frame, and a spring coupled between at least two of the base frame, the middle frame, the seat-and-back frame, and the back-and-head frame.

A foldable sofa-bed includes: a base with an internal cavity and a rear member; a foldable bed that includes separate and distinct head, intermediate and seat sections, each with a respective cushion, wherein in a folded position, the intermediate and seat sections are generally horizontally disposed and positioned in vertically stacked relationship, with the intermediate and seat cushions facing generally upwardly, and the head section is generally vertically disposed and positioned adjacent the rear wall of the base, and in an unfolded position, the head, intermediate and seat sections are generally horizontally disposed in serial alignment; and a bed folding mechanism that is attached to the base and the head, intermediate and seat sections that controls the movement of the bed between the folded and unfolded positions. In moving from the folded to the unfolded position, the intermediate section maintains generally the same orientation.
