A foldable sofa bed assembly is disclosed including first and second frame subassemblies, a side frame subassembly, a front frame subassembly adapted for connection to the side frame subassembly, a linkage subassembly for operatively interconnecting the first and second frame subassemblies and the side frame subassembly for moving the first and second frame subassemblies relative to each other and relative to the side frame subassembly between a folded sofa forming position and an open bed forming position. The subassemblies can be shipped in relatively narrow containers to be later assembled together. The linkage subassembly includes a plurality of pivotally connected links pivotally connected to the side frame subassembly and operable for movement between the sofa and bed forming position. The sofa bed assembly also includes a back frame subassembly adapted for connection to the side frame subassembly. The back frame subassembly includes a back wall and a backing subassembly which is pivotally connected to the back wall for movement relative thereto between a retracted storage position and an extended use position. The backing subassembly includes a plurality of interconnected back frame members pivotally connected to the back wall and capable of movement between the storage and use positions. The backing subassembly provides at least a partial support for a back cushion in the use position.
