When the frame 50 and platform 25 are placed within the recessed area 2, there is a continuous surface from the mattress 1 to the mini mattresses 27 on the platform.

(28) In the preferred embodiment, the mattress 1 is an alternating pressure mattress known in the art. An alternating pressure mattress comprising a plurality of inflatable side formations, located on both sides of the mattress, which can be inflated and deflated cyclically in a predetermined sequence. In a second embodiment, the mattress is a regular mattress with a recess area with the mini-mattresses made of similar material or foam.

(29) In the first and second embodiment, the electronic lift system or electronic pulley system rotates the lower half of the patient; the upper body may or may not have to be moved manually as determined by the degree of rotation. This allows for a more cost effective/economically feasible rotation/waste disposal system for lower-income nursing homes and caretakers in-home.

(30) In a third embodiment the mattress is a lateral rotation therapy mattress with a hole around the patient's pelvic area for waste disposal. The lateral rotation therapy mattress is known in the art. (See U.S. Pat. No. 5,375,273, Lateral rotation therapy mattress system and method, publication date Dec. 27, 1994, the disclosure of which is incorporated herein by reference). The lateral rotation therapy mattress includes: a plurality of side-by-side longitudinal air cells; and apparatus to supply pressurized air to the air cells to control the levels of pressure in individual ones of and/or groups of the air cells. The lateral rotation therapy mattress may have air cells divided into four groups: 1) left outer, 2) left inner, 3) right inner, and 4) right outer. Each air cell may be constructed of any suitable material such as compliant vinyl or urethane infused Nylon material. As an example, a patient may be laterally rotated about 30-45 degrees to the right by reducing the pressure in the right inner cells and increasing the pressure in the left inner cells. When it is desired to rotate the patient back to a supine position, the pressure in the right inner air cells are increased while the pressure in the left inner air cells are decreased until the pressure of both the right inner air cells and the left inner air cells are the same. When it is desired to rotate the patient to the left, the pressure in the right inner air cells are increased while the pressure in the left inner air cells are decreased. The rate of rotation is very slow and gentle so as not to wake the patient. The pressure control system for air support structure includes an air blower which supplies pressurized air to a main manifold which, in turn, provides air to air cells through a pressure regulator.
