Setup and Assembly Instructions
Assembly requires two adults. Follow these steps carefully:
- Unpack and Identify Parts: Lay out all components on a clean, soft surface (e.g., carpet) to prevent scratches. Refer to the parts list (not included in this document, typically found in the physical package) to identify each piece.
- Assemble Main Frame: Begin by connecting the headboards and footboards to the side rails for both the upper and lower bunks. Ensure all bolts are finger-tightened initially.
- Attach Ladders: Securely attach the two side ladders to the main bunk bed frame.
- Install Bed Slats: Place and secure the metal slats onto the support beams for both the upper and lower bunks. Ensure they are evenly spaced and firmly attached.
- Assemble Trundle Unit: Assemble the trundle bed frame, attaching the casters for smooth movement. Install the trundle bed slats.
- Final Tightening: Once all components are in place and aligned, fully tighten all bolts and screws using the provided Allen wrench. Do not overtighten.

Operating Instructions

- Using the Trundle Bed: The trundle bed is equipped with smooth-gliding casters. To use, simply pull the trundle unit out from under the lower bunk. To store, push it back into place until it is fully retracted.

Maintenance
Regular maintenance will help preserve the condition and safety of your bunk bed.
- Cleaning: Wipe the metal frame with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Hardware Check: Periodically (e.g., every 3-6 months) inspect all bolts, screws, and connections. Re-tighten any that have become loose.
- Slats Inspection: Ensure all bed slats are intact and securely in place. Replace any damaged slats immediately.
Troubleshooting
If you encounter any issues, refer to the following common problems and solutions:
- Squeaking Noises: This is often caused by loose connections. Re-tighten all bolts and screws on the frame.
- Trundle Not Gliding Smoothly: Check the casters for any obstructions (e.g., debris, carpet fibers). Ensure the casters are clean and properly aligned.
- Bed Feels Unstable: Verify that all frame components are correctly assembled and all hardware is fully tightened. Ensure the bed is on a level surface.
