When seated, the seat and the backrest of SPINA chair move automatically corresponding to user's sitting position or posture to best accomodate his/her lumbar. This epoch-making movement was achieved by newly developed mechanisms of the Passive Slide Seat (P.S.S) that prevents a harmful influence of half-seated posture, and the Active Lumbar Support (A.L.S) that supports your lumbar at any sitting position. These mechanisms follow any posture/position changes automatically during the sitting, requiring no adjustment. |
