A posturepedic buoyancy device for supporting a person lying on said device in water or on land in a manner to minimize postural strain comprises an inflatable mattress having attached thereto an inflatable lumbar elevation cushion 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 to receive and support a person's head when lying on top of the mattress. The recess is defined by opposing spaced-apart inflated mattress sections extending generally parallel to one another in the length direction of the mattress. The spacing between the mattress sections 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.
