This bed frame requires 2 people for assembly and takes approximately 60 minutes to complete. The most important rule during assembly is to half-tighten all screws into the holes first. Only after all screws are set should you fully tighten them with the provided tool. This ensures proper alignment and prevents structural issues.

Safety and Maintenance
- Keep the product away from fire or other heat sources.
- It is recommended to wear protective gloves during assembly.
- Use a pad or soft surface to avoid damaging the floor or the frame during assembly.
- Maintenance: Every 90 days, check that all nuts, screws, and knobs are securely fastened.
