Grahl SPS Duo-Back Type 11 with multi-lock titling action and weight tension control and knee tilt function.
Duo-Back® is equipped with a unique dual backrest, with the two elements moving independently of each other.
Height adjustable, the backrests correctly support the back of any user. The space between the pads allows the spine to move freely. Instead of putting pressure on the spine, support is evenly distributed throughout the back muscles.
The backrests are pivotally mounted enabling them to move in all three axes – forwards and backwards, up and down and left to right. The shape and mobility of the backrests ensures that they follow the contours of the back as it moves, stimulating muscle tone and blood circulation.
The special bowl shape formed by the two backrests provides optimal support. Every movement of the back leads to a counter movement of the backrests. This causes a massaging effect. Duo-Back® relieves pressure on the invertebral discs by approximately 50% more than standard backrests.
