A thoracic apparatus has upper and lower regions. The upper region may have a convex upper-back contacting region that may push the upper back of a user forward to encourage sitting with shoulders back in an open chest posture, and may have a central spinal accommodation. The lower region may have a recess to accommodate the lower lumbar region of the body in a position relatively rearwardly of the upper back. The apparatus may have a relatively stiff main member, and softer body members that contact the user's back that may have a dimpled or uneven surface. A lower portion may function as a stem positioning the upper region adjacent the upper back of the user. Fittings may secure the apparatus in a particular position, orientation, or location relative to a piece of furniture such as a chair or sofa. The back of the apparatus may have a no-slip fitting. |
