Abstract
An adjustable bed is particularly adapted for the care of morbidly obese patients and comprises a ground engaging frame with a mattress support including a head section, a center section and a foot section which are hingedly interconnected and have power devices which selectively drive lift arms to raise and lower the head and foot sections relative to the center section. To assist entry and exit of a patient onto and off of the bed, a foldable step arrangement is provided which is connected to the foot section and automatically unfolds as the foot section is tilted downward to form a step and folds compactly as the foot section is raised to a horizontal position.
