Abstract: A sleep sofa includes a main frame, a seat unit, a back unit and a supporting linkage assembly that can move the back unit along an arc to the front of the seat unit when the sleep sofa is converted to a bed state, the supporting linkage simultaneously lifting the rear side of the seat unit, which is mounted in the main frame to slope downwardly from horizontal at about a 5° angle, up to horizontal. Once positioned in front of the seat unit, the back unit can be pushed downwardly so as to rotate into a locked parallel orientation with the seat unit. The seat cushion of the seat unit and the back cushion of the back unit form the bedding surface. Pushing a back release tube will unlock the back unit to allow it to be returned to a sitting positioning above the seat unit (tilted rearwardly to define an angle of about 115° with the seat unit). During its arc movement over the seat unit, the back unit will rotate around pivots on the side backs thereof.

Abstract: A support assembly for a rocker-recliner chair which includes a base assembly having rocker cams and a support assembly mounted to the rocker cams and which can be shifted between a retracted state, and intermediate extended state and a fully extended state, the support assembly including left and right linkage subassemblies that each include a rocker mounting link, a backrest mounting bracket, a main carrier link pivotally connected to a front portion of the backrest mounting bracket, a back push link pivotally connected to a rear portion of the backrest mounting bracket, a roller lock tube mounting link pivotally connected at a first end to a rear end of the rocker mounting link, a roller lock tube push link pivotally connected between the roller tube mounting link and the back push link, and a roller lock tube connected between second ends of the roller lock tube mounting links of both linkage subassemblies to rest upon the base beneath the backrest mounting bracket to prevent rocking of the support assemb
