6. Operating
To ensure the longevity and safety of your bed frame, please adhere to the following operational guidelines:
- Ensure the mattress is properly centered and fully supported by the wooden slats.
- Do not exceed the maximum weight capacity of 350 lbs for the Twin size bed frame.

7. Maintenance
Regular maintenance will help keep your ZINUS Heidi Metal Platform Bed Frame in excellent condition:
- Cleaning: Wipe the metal frame with a soft, damp cloth. Avoid using abrasive cleaners or harsh chemicals, as these can damage the finish.
- Hardware Check: Every 3-6 months, inspect all bolts and screws. Tighten any loose connections to maintain stability and prevent squeaking.
- Slats Inspection: Ensure wooden slats are free from damage and properly seated within the frame. Replace any broken slats immediately.
8. Troubleshooting
If you encounter any issues with your bed frame, refer to the following common solutions:
- Squeaking Noises: This is often caused by loose hardware. Re-tighten all bolts and screws. Ensure all wooden slats are correctly positioned and the non-slip tape is intact.
- Mattress Sliding: The wooden slats are equipped with non-slip tape. Ensure this tape is clean and making proper contact with your mattress. If the tape is worn, consider replacing it or adding additional non-slip material.
- Instability/Wobbling: Verify that all frame connections are securely fastened. Check that the support legs are evenly touching the floor.
- Missing or Damaged Parts: If you find any parts missing or damaged upon arrival, do not proceed with assembly. Contact Zinus customer support immediately for assistance.
