5. Operating Instructions (Usage)
This bunk bed is designed for sleeping and light activities. Please observe the following for proper use:
- Accessing Upper Bunks: Use the integrated 4-step staircase for safe and comfortable access to the upper bunks. Do not climb on the frame or guardrails.
- Storage Stairs: Each wide step of the staircase doubles as built-in storage. These compartments are suitable for storing toys, books, shoes, or bedding. Ensure items are placed securely and do not obstruct movement.
- Upper Bunk Headboard Shelf: The upper bunk features a built-in headboard shelf. This space is designed for small, lightweight items such as a phone, glasses, books, a water cup, or a small lamp. Avoid placing heavy or unstable objects on the shelf.
- Mattress Placement: Place twin-sized mattresses on each bed platform. Ensure the mattress on the upper bunk does not exceed the recommended thickness to maintain guardrail effectiveness.

6. Maintenance
Regular maintenance helps prolong the life of your bunk bed and ensures continued safety.
- Cleaning: Wipe the metal frame with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish. For the wooden stairs, use a wood-safe cleaner if necessary.
- Hardware Check: Periodically check all bolts, screws, and connections to ensure they remain tight. Retighten any loose hardware to maintain stability and prevent squeaking.
- Slats Inspection: Inspect the metal slats for any signs of bending or damage. Replace any compromised slats immediately.
- Environmental Conditions: Avoid exposing the bed to extreme humidity or direct sunlight for prolonged periods, which can affect material integrity.
7. Troubleshooting
If you encounter any issues with your Bellemave bunk bed, refer to the following common problems and solutions:
- Squeaking Noises: Squeaking often indicates loose connections. Systematically check and tighten all bolts and screws on the frame and slats.
- Instability/Wobbling: Ensure the bed is placed on a level surface. Verify that all structural bolts are fully tightened. If wobbling persists, disassemble and reassemble, paying close attention to alignment.
- Damaged or Missing Parts: If you receive damaged parts or find components missing during assembly, do not proceed with assembly. Contact Bellemave customer support for replacement parts.
