A posturepedic buoyancy device (10) for supporting a person lying on said device in water or on land in a manner to minimize postural strain comprises an inflatable mattress (12) having attached thereto an inflatable lumbar elevation cushion (36) on the top surface of the mattress. The cushion elevates a person's lumbo-sacral region sufficiently to minimize hyper-extension in the lumbar region while lying prone on the mattress. To further facilitate prone positioning of the person in a comfortable correct posture, the head region of the mattress has an elongate recess (20) to receive and support a person's head when lying on top of the mattress. The recess (20) is defined by opposing spaced-apart inflated mattress sections (24, 26) extending generally parallel to one another in the length direction of the mattress. The spacing between the mattress sections (24, 26) is such to support a person's head by contacting the cheekbones while accommodating the mouth and nose area to permit free breathing while lying in the prone position.
