4. Setup and Assembly
Follow these steps carefully to assemble your MELOKEA Office Chair. It is recommended to have a second person assist with assembly.

- Install Gas Lift: Place the gas lift cylinder into the center hole of the assembled star base.
- Attach Mechanism Plate: Align the mechanism plate with the pre-drilled holes on the underside of the seat cushion. Ensure the front of the mechanism faces the front of the seat. Secure with screws using the provided Allen wrench.
- Connect Seat to Base: Carefully place the assembled seat cushion onto the gas lift cylinder, ensuring it is centered and stable.
- Attach Armrests: Secure the armrests to the sides of the seat cushion using the designated screws. Ensure they are oriented correctly (left and right).
- Attach Backrest: Align the backrest with the mounting points on the mechanism plate or armrests (depending on design). Secure with screws.
- Install Headrest: Slide the headrest into the designated slots at the top of the backrest. Adjust to your preferred height.
- Final Check: Once assembled, sit on the chair to engage the gas lift. Test all adjustments and ensure all screws are tight.
5. Operating Instructions
Your MELOKEA Office Chair offers several adjustments to customize your seating experience:
- Seat Height Adjustment: Locate the lever on the right side under the seat. To raise the seat, lift the lever while taking your weight off the chair. To lower the seat, lift the lever while seated.
- Recline/Tilt Adjustment: The lever on the left side under the seat controls the recline function. Pull the lever outwards to unlock the tilt mechanism, allowing the backrest to recline. Push the lever inwards to lock the backrest in an upright position.
- Tilt Tension Control: The round knob at the front center under the seat adjusts the tension of the tilt mechanism. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
- Lumbar Support Adjustment: The lumbar support can be adjusted vertically by sliding it up or down on the backrest. Some models may also offer depth adjustment via a knob.
- Armrest Adjustment: The armrests can be adjusted for height by pressing the button on the side of each armrest and sliding them up or down.

6. Maintenance and Care
Proper care and maintenance will extend the life of your MELOKEA Office Chair:
- Cleaning:
- For fabric or mesh surfaces, use a soft brush or vacuum cleaner to remove dust and debris.
- For spills, blot immediately with a clean, dry cloth. For stubborn stains, use a mild soap solution and a damp cloth, then wipe dry. Avoid harsh chemicals.
- For plastic and metal parts, wipe with a damp cloth and mild detergent if necessary, then dry thoroughly.
- Regular Inspection: Periodically check all screws, bolts, and connections to ensure they are tight. Retighten any loose fasteners to maintain stability and safety.
- Caster Care: Clean casters regularly to remove hair, dust, and debris that can impede smooth rolling.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fading and degradation of materials.
7. Troubleshooting
If you encounter issues with your MELOKEA Office Chair, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair does not adjust height. | Gas lift cylinder is faulty or lever is not engaged. | Ensure the height adjustment lever is fully engaged. If the problem persists, the gas lift may need replacement. Contact customer support. |
| Chair squeaks when moving. | Loose fasteners or friction between parts. | Tighten all screws and bolts. Apply a small amount of silicone lubricant to moving parts if necessary (avoiding casters). |
| Casters do not roll smoothly. | Debris (hair, dust) caught in casters. | Turn the chair over and carefully remove any debris from the caster wheels. |
| Backrest does not recline or lock. | Tilt lock lever is not engaged/disengaged properly or tilt tension is too high. | Ensure the tilt lock lever is in the correct position. Adjust the tilt tension knob counter-clockwise to loosen. |
