One or more supporting wings that are pivotally mounted to the axle members. A flexible sheet is mounted over the concave portion of the wings to support the patient. A mechanism for causing the wings to rotate is cooperatively coupled to the wings. Either mechanical, hydraulic or other equivalent mechanisms can be used to impart the rotation to the wings.
