The 2456 Comfort Posture Brace with Rigid Stays helps prevent the development of abnormal spinal curvatures from poor posture. It is the most effective way to prevent slouching and the long-term pain associated with it. It pulls the shoulders back and straightens the spine. With correct posture, spinal pressure on disks is relieved helping to reduce pain. For petite individuals it might serve as a substitute for a bulky thoraco-lumbar brace.
