- Do not exceed the maximum weight limit of 150 kg (330 lbs).
- Avoid standing on the chair or using it as a step stool.
- Keep children away from the assembly area. Small parts may pose a choking hazard.

3. Assembly Instructions
Assembly typically takes 5-15 minutes per chair. Follow these steps carefully:
- Unpack Components: Carefully remove all parts from the packaging. Lay them out on a soft, clean surface to prevent scratches.
- Attach Legs to Seat: Align each beech wood leg with the corresponding mounting points on the underside of the chair seat. Ensure the legs are oriented correctly, with the wider part facing outwards.
- Secure Legs: Insert the provided screws with washers into the pre-drilled holes. Hand-tighten all screws initially.
- Final Tightening: Once all legs are in place, use the Allen key to fully tighten all screws. Do not overtighten, as this may damage the wood.
- Check Stability: Place the assembled chair on a flat surface and gently test its stability. If it wobbles, check that all screws are evenly tightened.

6. Troubleshooting
If you encounter any issues, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair wobbles after assembly. | Screws are not evenly tightened. | Place the chair on a flat surface. Loosen all leg screws slightly, then sit on the chair to distribute weight evenly. Re-tighten all screws firmly. |
| Difficulty inserting screws during assembly. | Misalignment of parts. | Ensure the legs are correctly aligned with the mounting points. Do not force screws; gently adjust the leg position until the screw fits easily. |
| Squeaking noise during use. | Loose connections or friction between parts. | Check and tighten all screws. If the noise persists, apply a small amount of silicone lubricant to the joints where the legs meet the seat. |
