4. Operating Instructions
Using the Bunk Bed
- Upper Bunk Access: Use the integrated side ladders to safely access the upper bunk. The full-length guardrails provide protection against falls.
- Trundle Bed Operation: The trundle bed is designed to slide out from under the lower bunk. It features brakeable wheels. To use, unlock the wheels, pull the trundle out, and then lock the wheels to secure its position. To store, unlock the wheels, push the trundle back under the lower bunk, and lock the wheels.

Detaching into Three Individual Beds
This bunk bed can be conveniently separated into two individual twin beds and one trundle bed. This allows for flexible room arrangements as needs change.
- Disassemble Upper Bunk: Carefully remove the upper bunk from the lower bunk by unfastening the connecting hardware. It is recommended to have at least two adults for this step.
- Remove Ladders and Guardrails: Detach the ladders and guardrails from the upper bunk frame.
- Reconfigure: The lower bunk can now function as a standalone twin bed. The upper bunk, once separated and with guardrails removed, can also be used as a standalone twin bed. The trundle remains a separate, movable bed.

- Cleaning: Wipe the metal frame with a damp cloth. Avoid harsh chemicals or abrasive cleaners that could damage the finish.
- Fastener Check: Periodically (e.g., every 3-6 months) inspect all bolts, screws, and connections. Re-tighten any loose fasteners to ensure the bed remains stable and safe.
- Mattress Care: Follow the care instructions provided with your mattress.
