1. Safety Information
For safe use, ensure that the weight on the upper and bottom beds does not exceed 250 lbs, and the trundle bed should not exceed 250 lbs. Always use the built-in ladder and full-length guardrails on the top bunk to prevent falls. Inspect all parts before and during assembly to ensure there are no sharp edges or potential pinch points.
WARNING: Failure to follow these warnings could result in serious injury.
- Always use the recommended mattress size and thickness for each bed.
- Ensure all connections are securely tightened before use.
- Do not allow children under 6 years of age on the upper bunk.
- Periodically check and ensure that the guardrail, ladder, and other components are in their proper position and free from damage.

5.1 Using the Trundle Bed

5.3 Using the Ladder
The bunk bed is equipped with a built-in ladder for safe access to the upper bunk. Always use the ladder when climbing up or down. Ensure a firm grip on the ladder rungs and maintain three points of contact (two hands and one foot, or two feet and one hand) at all times.

6. Maintenance
- Cleaning: Wipe down the metal frame with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Fastener Checks: Periodically check all bolts and fasteners to ensure they remain tight. Re-tighten as necessary to maintain stability and safety.
- Mattress Care: Follow the manufacturer's guidelines for mattress care. Rotate and flip mattresses regularly to prolong their lifespan.
- Trundle Casters: Keep trundle casters free of debris to ensure smooth operation.
7. Troubleshooting
- Squeaking Noises: If the bed squeaks, check all bolts and connections. Tighten any loose fasteners. Applying a small amount of lubricant to metal-on-metal contact points can also help.
- Wobbly Frame: A wobbly frame usually indicates loose connections. Re-check and tighten all assembly hardware. Ensure the bed is on a level surface.
- Trundle Not Sliding Smoothly: Check the trundle casters for any obstructions (e.g., carpet fibers, dust). Clean the casters and ensure they are properly aligned.
- Missing Parts: If you discover any missing parts during assembly, refer to the 'Package Contents' section and contact Bellemave customer support for assistance.
