ABSTRACT:
A multi-stage adjustable double-person spring bed mattress structure including a bed tail pad, a fixed bed head pad, a bed face and a bed cover. Two pairs of U-shaped supporting frames are respectively oppositely passed through the clearances between the adjacent longitudinal springs under the metal rods near two lateral sides and the central portion. Two rotating devices are respectively disposed on opposite inner sides of rear ends of the connecting rods under the four U-shaped supporting frames. Two driving splines are passed through the central holes of the above members. When the driving spline is rotated by a rotary disk disposed on one side of the fixed bed pad and having an eccentrical handle, whereby the rotating tube is rotated and inclinedly moved up and down. An insertion seat having an insertion hole is connected on the center of the upper portion of the movable bed head pad, whereby two insertion legs of the pillow racks can be inserted in. By means of the rotary disk on outer side of the driving spline, the rotating device is rotated to drive the movable bed head pad to freely ascend or descend by any angle for lying horizontally or by other resting angle, the pillow can be two-stage 90 degrees rotated to lean on the movable bed head pad as a pillow or outward rotate and stretch into a pillow.
