Check your fit
Compare the seat and armrest dimensions with your desk and available space. Adjust the seat so your feet can rest on the floor or a suitable footrest, and leave room behind your knees. A load limit alone does not establish a comfortable fit.
After-sales questions & answers
How do I contact MELOKEA after-sales support?
For orders from melokea.com, email support@melokea.com. For Amazon orders, open Your Orders, select the order and choose Contact the Seller. Please include your order number, the PO or batch number on the label under the seat if available, a description of the issue, and clear photos or a short video. We normally reply within one business day; time zones, weekends and public holidays may affect response times.
What should I do if I receive a damaged or incorrect item?
Contact us promptly with your order number and photos of the item and packaging. Keep the received parts and packaging while we assess the issue. Do not use the chair if a structural part is damaged or the chair is unstable. We will confirm the appropriate next steps; if a replacement is unavailable, we will explain the available options.
My chair makes noise. What should I do?
Check the assembly against the instructions and make sure the screws and parts are fitted correctly. Tighten only as directed; do not overtighten or dismantle the gas lift. If the noise continues, send support@melokea.com a short video showing where it occurs. Stop using the chair if the noise is accompanied by instability or visible damage.
Why does my chair wobble?
Check that the chair is on a level surface and that the castors, base and screws are fitted as shown in the assembly instructions. If wobbling persists, stop using the chair and contact support with photos or a video. Do not attempt to repair a damaged base or gas lift yourself.
My new chair has a strong smell. What should I do?
Unpack the chair and air it in a well-ventilated room for two to three days. A mild packaging smell may reduce with ventilation, but we cannot guarantee a fixed disappearance time. If the smell remains strong or causes discomfort, stop using the chair and contact support.
A part has scratches or cracks. Is it safe to use?
A surface scratch and a structural crack are different issues. Send clear photos so we can assess the affected part. If you see a crack, deformation or damage to a load-bearing part, stop using the chair until support has advised you. We will assess whether a replacement part is needed.
Parts are missing from my order. What should I do?
Check the packaging and the parts list in the assembly instructions. Email support@melokea.com with your order number, the names or reference numbers of the missing parts, and a photo of the parts received. We will check the case and confirm how the missing components can be supplied.
The chair feels uncomfortable. What can I do?
Adjust the seat height and, where your model allows, the seat depth, backrest, lumbar support and armrests. Refer to the model’s instructions and take regular breaks. For help with the settings, send the model name and photos of the chair’s adjustment positions; you do not need to appear in the photos. If discomfort persists, stop using the chair and contact support to discuss the available options.

Product questions and answers
How does the seat-depth adjustment work?
The seat depth adjusts by 5 cm. Taller users can move the seat forward for more thigh support; shorter users can move it back to leave space behind the knees and maintain contact with the backrest.
What does the upgrade to 7D armrests provide?
The 7D armrests offer height adjustment, 360° dual-axis rotation, forward and backward movement, and three armrest-pad tilt settings (-10°, 0° and 20°). These armrest settings are separate from the four backrest recline lock positions.
Which backrest positions can be locked?
The backrest locks at 90°, 120°, 130° and 140°. The 30° dynamic lumbar support follows changes in posture.
Are the castors suitable for a quiet office?
The rubber castors swivel through 360°. The German product description states a noise level below 25 dB on parquet, tiles and carpet.
Which adjustments distinguish this model?
This model combines 7D armrests, seat-depth adjustment, a backrest with four locking positions and a 3D headrest.
