6. Maintenance

- Protection: Ensure the plastic protective pads on the legs are intact to prevent floor damage.
7. Troubleshooting
- Squeaking/Noise: If the bed frame produces noise, check all bolts and screws for tightness. The integrated foam padding on the central beam is designed to prevent metal-on-metal friction; ensure it is properly positioned.
- Instability: If the frame feels unstable, verify that all connections are fully tightened and that the frame is on a level surface. Ensure all legs are making firm contact with the floor.
- Mattress Sliding: The embedded design should prevent mattress sliding. If your mattress still slides, ensure it is correctly positioned within the frame's edges.
