摘要

Enhanced adjustable mattress bed essentially characterized in that it is constituted by a rectangular frame, preferably made of hollow tube, on which internally are coupled two analogous but unequal lengths in the form of a "U" that are articulated with suitable through means in the central zone of the frame, thus allowing its independent rotation and elevation with the corresponding front ends of these semibastidores related to the headboard and footboard by means of compass-like devices with variable aperture that allow to adjust its elevation and inclination, leaving an intermediate part, between the two semibastidores, which remains fixed and motionless.
