Operating and Usage
Using the Bunk Bed
- Upper Bunk: Access the upper bunk using the ladder. Ensure guardrails are always in place.
- Lower Bunk: The lower twin bed can be used as a standard bed underneath the upper bunk.
Dismountable Lower Bed Feature
The lower twin bed is designed to be dismountable, allowing for flexible room arrangements. To detach the lower bed:
- Remove the mattress from the lower bed.
- Carefully unfasten any connecting hardware that secures the lower bed to the main loft structure.
- Gently slide the lower bed out from underneath the upper bunk.
- The lower bed can now be used as a standalone twin bed elsewhere in the room, converting the main structure into a loft bed.
To reattach, reverse these steps, ensuring all connections are secure.
