The Giroflex 40-4049 combines breathable seating comfort with precise ergonomics. The mesh backrest ensures optimum air circulation and integrated lumbar support. The synchronous mechanism supports dynamic sitting, while seat depth adjustment, seat tilt adjustment and adjustable spring force allow fine adjustment to the body and working style. The chair is infinitely height-adjustable and optionally available with 3D armrests or without armrests. Hard floor castors glide quietly and gently on parquet and laminate. The two-zone seating concept promotes an active posture and provides noticeable relief. The design of the Giroflex 40 is a subtle nod to classics such as the Giroflex 313 and 353: rounded edges, all-round mesh fabric and unobtrusive controls convey a homely simplicity - behind this is sophisticated technology that provides first-class support throughout the working day.
