Operating Instructions
Your MELOKEA chair offers a range of adjustments to customize your seating experience. Familiarize yourself with these features for optimal comfort and ergonomic support.
1. Seat-Back Synchronization Technology
This technology ensures seamless coordination between the seat and backrest. As the backrest reclines, the seat cushion dynamically moves forward, maintaining consistent lumbar support and alignment with your body's movements. This helps relieve lower and upper back pain, and hip discomfort.
Figure 3: Illustration of the Seat-Back Synchronization, showing how the seat cushion moves forward as the backrest reclines to maintain ergonomic support.
2. Adaptive Lumbar Support (2nd Gen Flexback)
The innovative adaptive lumbar support adjusts dynamically up, down, left, and right within a 0-15° range, responding to your lower back movements. It provides continuous support regardless of your sitting posture or body rotation.

3. Unlimited Levitation (Recline)
Enjoy unlimited levitation at any desired angle without manual insertion or detachment. The chair offers five levels of maximum tilt adjustment. You can also adjust the tilt tension to match your personal preferences. Note: The seat tilt does not support locking, but allows for easy hovering at any angle.

4. Adjustable Features: Headrest, Armrests, Seat Depth, Backrest Height
- 3D Headrest: Adjust the headrest up to 12 cm in height, 7 cm in forward/backward position, and pivot it 90°.
- 4D Armrests: The extra-wide armrests offer multiple adjustment options: forward/backward glide, height adjustment, lateral movement, and a 15-degree pivot.
- Seat Depth: The seat depth can be customized by 50 mm to accommodate different leg lengths.
- 4-Level Backrest Adjustment: Allows for precise positioning of lumbar and upper back support, ensuring an optimal fit for your height.

5. Waterfall Edge Seat Cushion
The seat cushion features a waterfall edge design, composed of molded foam and a thick latex layer. This design helps relieve thigh pressure, improves blood circulation, and enhances overall posture, ensuring a soft, comfortable, and hygienic seating experience.

Maintenance and Care
Proper care will extend the life and maintain the appearance of your MELOKEA office chair.
- Cleaning: For mesh and fabric surfaces, use a soft cloth dampened with mild soap and water. Avoid harsh chemicals or abrasive cleaners. For aluminum parts, wipe with a dry or slightly damp cloth.
- Latex Cushion: The integrated antibacterial latex cushion is designed for hygiene. Avoid exposing it to direct sunlight or extreme temperatures.
- Regular Inspection: Periodically check all screws, bolts, and moving parts to ensure they are secure and functioning correctly. Tighten any loose fasteners.
- Avoid Overloading: Do not exceed the maximum weight capacity of 200 kg.
Troubleshooting
If you encounter any issues with your MELOKEA chair, please refer to the following common troubleshooting tips:
- Chair Squeaks or Wobbles: Ensure all assembly screws are tightly secured. Apply a small amount of silicone lubricant to moving parts if necessary, avoiding contact with fabric.
- Gas Lift Not Adjusting Height: Check if the height adjustment lever is fully engaged. Ensure no obstructions are preventing the gas lift from moving freely.
- Backrest Does Not Stay in Position (Recline): The "unlimited levitation" feature allows for free movement and pausing at any angle, but does not feature a locking mechanism for the recline. Ensure the tilt tension is adjusted to your preference.
- Armrests Adjust Too Easily: While 4D armrests offer extensive movement, if they feel excessively loose, check for any visible loose connections.
- Headrest Constantly Adjusts: The 3D headrest is designed for dynamic movement. If it does not hold a position you expect, ensure you are using its full range of motion for adjustment.
If the problem persists after attempting these solutions, please contact MELOKEA customer support for further assistance.
