ABSTRACT:
A bed comprises a base framework, an intermediate framework and a mattress framework which comprises a central frame, a head frame and a foot frame. Main rams connect the intermediate framework to the base framework for raising and lowering and tilting the intermediate framework relative to the base framework. The rams pivotally engage the intermediate framework by shafts. The ram is rigidly mounted to the main framework. A pivot frame pivotally mounts the ram about a pair of pivot axes relative to the base framework to accommodate tilting of the intermediate framework.
