The present invention is portable lifting apparatus for raising a supine bipedal user into a sitting position with the assistance of sequentially inflated bodies. This device includes a sectional cot, a plurality of inflatable bodies, and a rigid, foldable, locking frame. The addition of the frame, as opposed to the sole use of the inflatable bodies, provides additional stability for the apparatus during the rescue process. Further, due to the rigidity of the frame, it allows another person to lift and carry the apparatus with the patient on it. The apparatus may also include collapsible armrest for use by the patient. The inflatable bodies may inflate simultaneously, resulting in a rapidly raising the patient to a sitting position.
