The Back Bubble comes in Patient and Physician models, both with multiple options for mounting the device so it hangs from your ceiling or doorway. The Physician model comes with a chin-up bar suspension system, while the Patient model includes a heavy-duty hook. It consists of an air-filled body harness and a buoyancy spring that, despite how it looks in the photos, the brand says feels "like floating in air-cushioned weightlessness." The Back Bubble provides spinal decompression, back stretching, and back traction in multiple planes and positions, including kneeling, upright, leaning, reclining, shoulder stand, and full inversion. Hey, if it stretches my spine, restores traction, and relieves my lower back pain, I don't care what kind of poon the Back Bubble makes me look like while I'm using it. Adult male in a baby carrier.
