Your MELOKEA office chair offers multiple adjustment options to customize your seating experience for optimal comfort and ergonomic support.

5.1. Seat Height Adjustment

To adjust the seat height, pull the lever located on the right side of the seat upwards. While holding the lever, stand up to raise the seat or remain seated to lower it. Release the lever at your desired height.

5.2. Dynamic Lumbar Support

The chair features an innovative dynamic lumbar support system that automatically adapts to your body shape and movements. No manual adjustment is required for the lumbar support; it provides continuous support to your lower back as you shift positions.

The 2D headrest is adjustable in height and rotation:

• Height Adjustment: Grasp the headrest and slide it up or down to your preferred height (up to 8 cm adjustment range).
