A sofa bed assembly comprises a carcass having an inside, outside and interstitial interface. Mechanical moving parts comprise a bed base mount assembly and gas strut all outside the carcass and interface mounted. A base supports a mattress held by base sidewalls, vertical within and filling the carcass with the sofa bed closed. An armrest supports a sitter's arm in the closed assembly and as is a proximal bed support in the open assembly. Pivoted leg supports at the end of the bed base rotate as distal bed supports. Alternatively, a sofa is moved to the end of the bed base as distal bed support. An armrest extension extends the armrest for the closed assembly and folds through 90 for the open assembly allowing the armrest to act as the proximal bed support. Armrest shields cover mechanical moving parts.

A seat 100 moveable between a seat configuration and a bed configuration, the seat 100 comprising a squab 120 including upper and lower cushions 126, 124, a conversion mechanism configured to move the squab 120, for converting the seat 100 between the seat and bed configurations, and a backrest 122 connected to the squab 120 or conversion mechanism, for moving with the squab 120, the squab 120 being laterally displaceable by the conversion mechanism between a first position in the seat configuration and a second position in the bed configuration, and the backrest 122 being configured to occupy a space at an end of the squab 120 which is made available by lateral displacement of the squab 120 into the second position, and the upper cushion 126 of the squab 120 being movable relative to the lower cushion 124 for covering the backrest 122 in the bed configuration.

A mattress that is convertible into a sofa has a first side section, a second intermediate section hingedly connected to the first side section, and a generally c-shaped third side section, hingedly connected to the second intermediate section. The first side section is foldable under the second intermediate section at the hinged connection between them, and third side section is foldable to over the second intermediate section at the hinged connection between them, to form a sofa, with the second intermediate section forming the seat of the sofa, and the C-shaped third side section forming arms and a back surrounding the seat.

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 folding bed system includes a bed frame having a head section, a center section, and a foot section. The center section is connected to first and second slide mechanisms, and the head section is connected to first and second guide mechanisms. The slide and guide mechanisms are connectable to opposed walls of a structure. In some embodiments, a hinge assembly for a folding structure includes a center post securable to the center section, and a connecting bracket movably coupled with the center post that is vertically displaceable on the center post between a down position and an up position. A forward bracket is secured at one end to the connecting bracket and is securable at an opposite end to the head section, and an aft bracket is secured at one end to the connecting bracket and is securable at an opposite end to the foot section.
