An adjustable bed comprises separately articulatable and rotatable sections. These sections are operable to be articulated and rotated to facilitate a patient's entrance or exit to or from the bed. To facilitate entrance or exit, the torso section is articulated to a substantially upright or chair-like position. Next, the torso section is tilted, either to the right or to the left, to facilitate patient entry or exit. During the first part of this tilting motion, the lower thorax support region of the torso section is extended more than the shoulder support region to help rotate the patient into an exiting position. During the second part of this tilting motion, the shoulder support region is then hyperextended to help drive the patient off of the bed. A separately rotatable lower leg section may also be tilted in the same direction to further facilitate patient entry or exit.
