The SitagXilium DuoBack combines ergonomic design with modern technology and makes long periods of sitting noticeably more comfortable. The DuoBack backrest consists of two movable wings that flexibly adapt to the back, stabilize the spine and significantly relieve the lumbar region - ideal for people with sensitive backs or disc problems. The synchro-mechanism with automatic weight adjustment supports natural changes in posture and keeps the movement of the seat and back in balance. Seat depth and seat tilt adjustment are available for personal fine-tuning; 4D armrests can be adjusted in height, width, depth and rotation angle and bring the forearms relaxed in line with the keyboard and mouse. Carefully crafted in Swiss quality, the SitagXilium DuoBack combines durability, precise adjustability and noticeable comfort - for a working environment that promotes health and concentration.
