Abstract: Therapy cushions are provided having angular body supporting surfaces. The cushions can be juxtapositioned to orient patients in various positions for achieving effective bronchial drainage. First and second cushions have two adjoining 90.degree. abutment surfaces with corresponding abutment corners. Each of the surfaces terminate at flattened end areas from which extend body-contacting sloping portions. The sloping portion of one cushion is indented and includes a predetermined inclined surface. A wedge cushion may be used to tilt the patient.
