Operating Instructions
Using the Trundle Bed
The trundle bed is designed for convenient extra sleeping space. It features four wheels for easy movement. To use, simply pull the trundle unit out from under the lower bunk. To store, push it back into place until it is fully under the bed.
Utilizing Storage Staircase
The integrated staircase provides safe access to the upper bunk and includes open shelves for storage. These shelves can be used to store books, toys, or other small items, helping to keep the room organized.

Maintenance and Care
- Cleaning: Wipe surfaces with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the finish.
- Hardware Check: Periodically check all bolts, screws, and connections to ensure they remain tight. Retighten as necessary to maintain stability and safety.
- Wood Care: Protect the wood from direct sunlight and extreme temperature changes to prevent warping or cracking.
Troubleshooting
Loose Connections / Instability
If the bed feels wobbly or unstable, re-check all assembly hardware. Ensure all bolts and screws are fully tightened. Do not overtighten, as this can strip the wood.
Squeaking Noises
Squeaking can often be resolved by tightening all hardware. If squeaking persists, disassemble the affected section, apply a small amount of paraffin wax or silicone spray to the joints, and reassemble.
Trundle Not Rolling Smoothly
Check the trundle wheels for any obstructions or debris. Ensure the wheels are properly installed and not damaged. Clean the floor area where the trundle operates.
