- Unpack and Identify Parts: Carefully remove all components from the packaging. Refer to the included parts list and diagrams to identify each piece.
- Assemble Lower Bunk Frame: Connect the side rails to the headboard and footboard of the lower bunk using the provided hardware. Ensure all connections are secure but do not fully tighten bolts until the frame is stable.
- Install Lower Bunk Slats: Place the wooden slats onto the support rails of the lower bunk. Secure them with screws as indicated in the diagram.
- Assemble Upper Bunk Frame: Repeat the process for the upper bunk frame, connecting side rails to the headboard and footboard.
- Attach Upper Bunk to Lower Bunk: Carefully lift the assembled upper bunk frame and align it with the designated connection points on the lower bunk posts. Secure with the appropriate bolts. Assistance is highly recommended for this step.
- Install Upper Bunk Slats: Place and secure the wooden slats for the upper bunk.

Using the Trundle Bed:
The trundle bed is designed for convenient additional sleeping space. To use, gently pull the trundle unit out from under the lower bunk. The wheels allow for smooth movement. To store, push the trundle unit back under the lower bunk until it is fully recessed.
Accessing the Upper Bunk:
Always use the integrated ladder to access the upper bunk. Ensure the ladder is stable before climbing. Descend the ladder facing the bed.
6. Maintenance
- Cleaning: Dust and clean the bed frame with a damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the finish.
- Hardware Check: Periodically inspect all screws, bolts, and connections. Tighten any loose hardware to ensure the bed remains stable and safe.
- Wood Care: The bed is made of solid pine wood and MDF. Protect it from extreme temperature changes and direct sunlight to prevent warping or cracking.
7. Troubleshooting
Common Issues and Solutions:
- Bed feels wobbly after assembly: Ensure all bolts and screws are fully tightened. Re-check each connection point according to the assembly instructions.
- Missing or damaged parts: Refer to the parts list in your assembly manual. Contact Polibi customer support with the specific part numbers for replacements.
- Difficulty with assembly steps: Review the diagrams and instructions carefully. If a step is unclear, try re-reading it or contacting customer support for clarification. Having a second person assist can significantly ease the assembly process.
