- Ventilation: Ensure adequate ventilation around the bed.
- Age Recommendation: Bunk beds are not recommended for children under 6 years of age on the upper bunk.

3. Setup and Assembly Instructions
Assembly requires at least two adults. Clear a spacious area for assembly. Do not use power tools for tightening hardware as this may damage the wood.
General Assembly Steps:
- Unpack and Identify Parts: Carefully remove all components from the packaging. Lay them out and compare with the parts list in the separate assembly guide to ensure all pieces are present and undamaged.
- Assemble Bed Frames: Begin by assembling the headboards and footboards for both the upper and lower beds. Attach the side rails to form two separate twin bed frames.
- Install Slats: Place and secure the wooden slats onto the support ledges of each bed frame. Ensure they are evenly spaced and firmly attached.
- Stack Beds (for Bunk Bed Configuration): Carefully lift and place the upper bed frame onto the lower bed frame, aligning the connection points. Secure them using the provided hardware.
- Attach Guard Rails: Install the guard rails on all open sides of the upper bunk. Ensure they are securely fastened.
- Attach Ladder: Securely attach the inclined ladder to the designated side of the bunk bed. Verify it is stable and does not wobble.

2-in-1 Convertible Design:
This bunk bed is designed to be convertible. It can be used as a traditional twin-over-twin bunk bed or separated into two individual twin beds. To convert, carefully disassemble the upper bunk from the lower bunk and reconfigure the headboards/footboards as needed for two standalone beds. Ensure all hardware is properly secured in either configuration.
