At a first glance, this office chair looks strange but its main purpose is to adapt itself to spine’s shape. It is possible thanks to the implemented 11 torsion spring-loaded bearing joints, exactly impressing your spine. This ergonomic and orthopedic device is especially useful for people who spend a lot of time sitting. In order to improve your sitting comfort it is only necessary to lean back and program your ideal posture, so that over the time “muscle memory” permanently improves your circulation and entire back structure. -Kiril-
