Assembly of the Onyx Ergo Posture Chair involves connecting the star base, gas lift, and mechanism to the seat structure using the provided hardware. Once assembled, ensure the chair is placed on a level surface. To maintain the chair, vacuum the fabric upholstery weekly to prevent dust accumulation in the foam pores. Wipe down the plastic components with a damp cloth and mild soap; avoid harsh chemicals that may degrade the finish. Periodically check that all tension knobs and screws remain tight, especially after the first month of use. The chair is compatible with standard office floor mats to protect carpeting or hardwood floors from caster marks.
