Operating Instructions

Your MELOKEA Ergonomic Office Chair offers multiple adjustment features to customize your seating experience for optimal comfort and support.

• Seat Height Adjustment: Locate the lever on the right side under the seat. Pull the lever up to raise the seat. To lower, pull the lever up while seated. Release the lever at the desired height. The seat height is adjustable up to 10 cm.
• Seat Depth Adjustment: This chair allows for a 5 cm adjustment in seat depth. Locate the lever or knob under the seat (specific location may vary, refer to diagram if available). Adjust to relieve pressure on the thighs and ensure proper posture.

  Adjust armrests to support your arms comfortably, keeping your shoulders relaxed.

Maintenance

Regular maintenance will help prolong the life and appearance of your MELOKEA Ergonomic Office Chair.

• Hardware Check: Periodically check all screws, bolts, and connections to ensure they are tight. Retighten any loose hardware to maintain stability and safety.
