Maintenance
To maintain the quality and longevity of your ZINUS SmartBase bed frame, follow these simple care instructions:

Troubleshooting
If you encounter any issues with your ZINUS SmartBase, consider the following common solutions:
- Squeaking Noises:
- Ensure all legs are fully extended and locked into place.
- Verify that the mattress is properly centered on the frame and not causing uneven pressure.
- Check for any loose connections or bolts and tighten them if necessary.
- Frame Instability:
- Confirm that the frame is placed on a flat, level surface.
- Inspect all support legs for proper extension and locking.
- Ensure the two frame sections (for larger sizes) are securely connected.
- Difficulty Folding/Unfolding:
- Ensure no obstructions are preventing the frame from folding or unfolding smoothly.
