4. Maintenance
To ensure the longevity and continued performance of your Zinus Rumi bed frame, follow these simple maintenance guidelines:
- Regular Cleaning: Wipe down the metal frame with a soft, damp cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish.
- Check Connections: Periodically inspect all bolts and connections to ensure they remain tight. Over time, normal use can cause bolts to loosen, which may lead to squeaking or instability. Tighten any loose bolts with the provided ratchet or an appropriate tool.
- Avoid Excessive Weight: While the frame has a high weight capacity, avoid placing excessive or uneven weight on the frame, especially during movement or assembly.
- Protect Floors: The frame feet are designed to be gentle on floors. However, if moving the frame, lift it rather than dragging to prevent scratches. Consider placing felt pads under the legs for added protection on delicate flooring.
