Usual office chairs often limit the natural mobility of backrest and spinal column. Because of the innovative design principle of the backrest wings, the duo-back balance® actively adapts to any move- ment of the upper part of the body. Not only forwards and backwards but also sideward and in the direct axis.
The unique balance effect supports the complex system of back muscles, spinal column, sacral bone, tail bone, ligaments and intervertebral discs and allows for dynamic sitting without tiring. Due to the permanent torsion of the spinal column, incorrect weight bearings and muscular tensions mainly in the lumbar region are avoided. And so the dangerous chronic manifestation of back pains can be effectively prevented.
