6. Maintenance
- Cleaning: Wipe the metal frame with a damp cloth and mild detergent. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Fastener Check: Periodically (e.g., every 3-6 months) inspect all bolts and screws to ensure they are tight. Re-tighten as necessary to maintain stability and prevent squeaking.
- Floor Protection: Ensure the silicone foot caps are intact and in place to protect your floors from scratches. Replace if damaged.
- Weight Distribution: Avoid placing excessive, concentrated weight on any single point of the frame. Distribute weight evenly across the mattress.
7. Troubleshooting
- Noise after installation: This is typically caused by poorly fitted parts or loose screws. Please check and fasten all connections and screws. If noise persists, ensure all components are correctly aligned according to the manual.
- Mattress sliding: Ensure the four mattress stoppers are correctly installed and facing outwards to secure the mattress.
- Damaged or missing parts: If any defects or missing accessories are found upon delivery, contact the seller immediately for replacement parts.
