OC 58 – Office swivel chairs

Light. Balanced. For every posture.

The OC 58 is a lightweight office chair with a self-weighting synchro mechanism — it follows every movement without needing readjustment. Available with mesh back or upholstered back, frame in black or white.

The OC 58 impresses with its consistently lightweight construction: the base is made of high-performance nylon, the armrests are reduced to a minimum of material yet remain stable. At the heart of the chair is a self-weighting synchro mechanism that automatically adapts to body weight and seating posture — no manual counterforce adjustment required.

The armrests can be individually adjusted in height, width and angle and feature a soft-touch pad. The seat is directly foamed for lasting shape stability, with a rounded front edge that relieves pressure behind the knees during long periods of sitting.

Available in two back variants: with breathable mesh upholstery or as a fully upholstered plastic shell — each with a black or white frame.
