• S-Back, the so-called “chair on a chair” designed to be used on a chair, is the world's first chair combined with an LSP (lumbar support pad) that works on the waist and hip at the same time and helps one sit comfortably on a chair in a correct sitting posture using the user’s own weight. S-Back’s floor piece and LSP are flexible enough to be moved back and forth as well as sideways by the body’s movement. In other words, when the body weight moves downwards to sit on it, S-Back’s LSP moves forward while supporting the lumbar area by the law of action and reaction.
• Therefore, the LSP is always located around the hip during the movement of the body and pressed against the waist and performs the function of preventing the body’s posture from being in disalignment or the back being slightly bent. Users do not feel uncomfortable while sitting on the S-Back for a long duration since the ergonomically designed main body of the S-Back lifts up the pelvis while aligning it towards the center of the LSP, which prevents the hip bone from bearing the whole weight. So, the user feel so comfortable from the moment he/she sits on this chair.
• And it offers unvarying sitting comfort for a long duration as it evenly distributes the body weight to several parts of the body that is normally applied to the waist and pelvic area.It is especially beneficial for office workers who have to sit on a chair for long hours, students, examinees, drivers who drive for long hours, long distance travelers, those sitting during a religious service, meditators, people who enjoy lots of outdoor activities such as yoga, fishing and mountain climbing, those suffering from back pain and women who are pregnant or gave birth.
