Care Instructions

To keep your ergonomic office chair in top condition, regularly dust with a soft cloth and vacuum fabric surfaces using a brush attachment. Spot clean spills immediately with a damp cloth and mild detergent—avoid harsh chemicals or abrasives. Check and tighten screws or adjustment knobs periodically to maintain stability. For smooth movement, clean the caster wheels and lightly lubricate if needed. Keep the chair away from direct sunlight and excessive moisture to preserve the upholstery and frame.
