Abstract
An articulated bed convertible to a chair position is described. The bed comprises a mattress formed by a backrest section, a seat rest section and a leg rest section. The mattress backrest section and seat rest section are secured to a support frame. Articulating linkages are secured to the frame to articulate the sections. The support frame is elevated from a floor surface by a frame assembly having legs or casters to engage with a floor surface. The leg rest section of the mattress is secured to a retractable support frame. The mattress has at least a compressible section formed of compressible material. Compressible interconnecting members compress the compressible material to shorten the length of the compressible section. The compressible material is restrained as it is compressed and decompressed when the support frames are displaced from a horizontal position to an articulated chair position.
