An adjustable bed which includes a first frame and a second slide frame upon and relative to the first frame. The first frame includes side guides along which roll rollers carried by slide rails of the slide frame. The slide frame includes a backrest frame, a seat frame and a thigh/leg frame. The backrest frame is defined by opposite pairs of head arms and back arms transversely connected by crossbars between the head arm and between the back arms. A pair of extendable/retractable members are connected one to each of the crossbars. The extendable/retractable members are relatively extended in a first position in which the backrest frame, seat frame and thigh/leg frames are disposed in a substantially horizontal plane and a second position in which the backrest frame is raised and the seat frame is closer to a head end of the frame. The thigh/leg frame is also defined in part by a pair of legs which are moved between a first position in substantial horizontal relationship and a second position angulated thereto. Extendable and retractable members move the pair of legs between the first and second positions by moving from a retracted position and vice versa.

[ What is claimed is:] [1.]1. An adjustable bed frame comprising a first frame having substantially remote frame head and frame foot ends, a slide frame mounted for reciprocal sliding movement relative to said first frame, said slide frame including opposite side slide rails each having opposite head and foot ends, a backrest frame adjacent said first frame head end, said backrest frame including at least one pair of head and back arms, first pivot means for pivotally connecting first ends of said head and back arms to each other, second pivot means for pivotally connecting a second end of said head arm to said first frame head end, third pivot means for pivotally connecting a second end of said back arm to at least one of the side slide rail head ends, a backrest frame and slide frame drive assembly for simultaneously moving said backrest frame and slide frame from a first substantially aligned horizontal first position to a second position at which said slide frame is closer to said frame head end than when in said first position and said backrest frame is at least partially raised, and said drive assembly including drive means connected between said head and back arms for pulling said head and back arms from a substantially horizontal planar 180.degree. position relative to each other in said first position to the second position at which said head and back arms define a relatively acute angle therebetween in said second position and reversing movement from said second position to said first position by pushing said head and back arms relative to each other.
