6. Maintenance
- Cleaning: Wipe the bed frame with a dry cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive cleaners, which can damage the wood finish.
- Hardware Check: Periodically inspect all bolts, screws, and connections to ensure they remain tight. Retighten as necessary to maintain structural integrity and safety.
- Wood Care: The bed is crafted from solid pinewood. Protect it from extreme temperature changes and direct sunlight to prevent warping or fading.
7. Troubleshooting
- Missing or Damaged Parts: If you find any parts missing or damaged upon opening the package, do not proceed with assembly. Contact Tatub customer support immediately for replacement parts.
- Difficulty Assembling / Misaligned Holes: Some users have reported challenges with assembly due to misaligned or missing pre-drilled holes. If you encounter this, do not attempt to force parts. Contact customer support for guidance. Drilling new holes without proper instruction may void your warranty or compromise safety.
- Bed Feels Unstable: Ensure all hardware is fully tightened. If the bed still feels unstable, re-check the assembly steps to confirm all components are correctly installed.
