Maintenance
To maintain your HOBINCHE bed frame, simply wipe it with a damp cloth as needed. Avoid using harsh chemicals or abrasive cleaners that could damage the finish. Regularly check all fasteners to ensure they remain tight for continued stability and noise-free performance.

- Instability/Wobbling: Verify that all frame components are correctly aligned and securely fastened. Check that the bed frame is placed on a flat, even surface.
