How to use

Adjust the seat height so your feet rest flat on the floor and your knees are at approximately 90 degrees. Set the backrest and tilt mechanism to provide comfortable lumbar support while allowing slight movement; lock the tilt when a stable upright position is needed. Use armrests if fitted at a height that keeps your shoulders relaxed and forearms roughly parallel to the desk surface. Regularly check and tighten visible fastenings to maintain stability.

Usage recommendations

For best results, position the chair at the correct desk height and alternate sitting positions periodically. Clean the polyester fabric with a soft brush or vacuum; treat spills promptly with a damp cloth and mild detergent. Follow manufacturer instructions for assembly and safety limits regarding user weight and adjustment ranges.
