How to use

Adjust the seat height using the lever beneath the seat so that your feet rest flat on the floor and your knees form approximately a 90-degree angle. Position the chair close enough to the work surface to avoid leaning forward; the contoured backrest should support the natural curve of your lower back. Use the casters to move between work areas and avoid dragging the chair to protect floor coverings. Periodically check and tighten any visible fasteners to maintain stability.

Usage recommendations

For extended daily use, combine correct seat height with regular short breaks and occasional posture changes. Clean leather surfaces with a soft, damp cloth and use leather-appropriate care products occasionally to maintain appearance and durability. Avoid exposure to direct sunlight for prolonged periods to prevent premature fading.
