Comfortable high-back swivel chair with a comfort mechanism. Stepless seat height adjustment with top lift. This model carries the GS mark of the LGA Nürnberg and meets all safety requirements for office and contract use according to DIN EN 1335 part 1-3. Synchronous mechanism, 4-fold lockable, individually adjustable to body weight. Extra high and wide, contoured backrest with spine shaping, continuously height-adjustable. Intervertebral disc seat: The front part sinks flat, while the rear seat part rises sharply, thus supporting the pelvis for an ergonomic sitting posture. Includes height-adjustable armrests. High-quality, pleasant to the touch cover. Shapely and stable black plastic base. Equipped with load-braking safety double castors for carpet floors, allowing the chair to roll only under load; in an unloaded condition, the wheels brake to prevent unintended rolling away.
