Backjoy Sitsmart core back support

BackJoy SitSmart is an innovative sitting device that naturally relieves back pain by optimizing your sitting posture.
If you sit for long periods of time, posture support is key. SitSmart is a simple posture corrector that restores the natural curvature of the spine to relieve lower back pain. Without SitSmart, your muscles flatten and tense under your body weight, causing pain.
