Reduce back pain with active sitting

Back pain is often the result of weak stabilizing muscles. By creating an unstable surface, your joints and muscles react to keep you stable on the Balance and Therapy Wedge, firing up your abdominals, working those deep stabilizers that support your spine and low back. Using the wedge while seated at your desk is a great way to rehabilitate and prevent back pain and improve spinal health.

Keep the blood flowing while you sit

Maintaining balance during active sitting, drives the heart to pump blood a bit faster than sedentary sitting and the blood vessels in the legs and hips open up increasing blood flow further. Better blood flow drives more oxygen to the brain which keeps the mind sharp and focused.
