The Giroflex 545 supports ergonomic sitting with a smooth, precise mechanism. The synchro-mechanism promotes gentle posture changes and the rocking function can be adjusted to the body weight. A height-adjustable backrest provides precise support and can be locked in place if required. The seat depth adjustment optimizes the thigh support - for relaxed, upright working for many hours. Durable materials and careful workmanship round off the comfort.
