2. Safety Information
Adherence to the following safety guidelines is crucial for preventing injury and ensuring the longevity of your bunk bed. Failure to follow these instructions may result in serious injury.
- Weight Capacity: The upper bed has a maximum weight capacity of 250 lbs. Each lower bed has a maximum weight capacity of 350 lbs. Do not exceed these limits.
- Mattress Thickness: For the upper bed, a mattress thickness of 6 inches is recommended. For the bottom beds, a mattress thickness of 8 inches is recommended. Ensure the mattress on the upper bunk is not too thick, as it must remain below the top edge of the guardrails.
- Guardrails: The upper bed is equipped with guardrails on all four sides. These are essential for preventing falls. Do not remove or modify them.
- Ladder Use: Always use the provided ladder for accessing the upper bunk. Do not use chairs or other furniture. Ensure the ladder is securely attached before use.
- No Jumping: Do not allow jumping or rough play on the bunk bed.
- Assembly: Ensure all parts are correctly assembled and all fasteners are tightened before use. Periodically check and re-tighten fasteners as needed.
- Ventilation: Ensure adequate ventilation around the bed.
- Children: The upper bunk is not suitable for children under 6 years of age.

4. Setup and Assembly Instructions
Assembly is required for this product. It is recommended that two adults assemble the bed. Please follow the step-by-step instructions provided in the included assembly manual. All necessary tools are included.
- Unpack and Identify Parts: Carefully unpack all components from both packages. Lay them out on a clean, soft surface (like a carpet) to prevent scratches. Refer to the parts list in your separate assembly manual to identify each piece.
- Assemble Lower Bed Frames: Begin by assembling the two individual twin bed frames for the lower level. Connect the side rails to the headboards and footboards using the provided hardware. Ensure all connections are secure but do not fully tighten until all parts are aligned.
- Install Slats for Lower Beds: Once the frames are stable, insert the metal slats into the designated slots on each lower bed frame. These slats provide mattress support and eliminate the need for a box spring.
- Assemble Upper Bed Frame: Construct the upper Twin XL bed frame, including its side rails and end panels. Note the integrated shelf on one side, which can be used for storage or to extend the bed to Twin XL size.
- Attach Support Posts: Connect the vertical support posts to the lower bed frames and then to the upper bed frame. These posts provide the structural integrity for the bunk configuration.
- Install Guardrails: Securely attach the guardrails to all four sides of the upper bunk. These are critical safety features.
- Attach Ladder: Mount the ladder to the designated attachment points on the upper bunk. Ensure it is firmly secured and stable.
- Final Tightening: Once all components are in place and aligned, systematically tighten all screws, bolts, and fasteners using the provided Allen wrench. Do not overtighten.

5. Operating Instructions
The DERCASS Metal Triple Bunk Bed offers flexible configurations to suit your needs.
- Standard Bunk Bed Configuration: The bed is designed as a Twin XL over Twin & Twin L-shaped bunk bed, providing sleeping space for three.
- Separable Beds: This triple bunk bed can be separated into three individual twin beds. To do this, carefully disassemble the upper bunk from the lower frames and detach the connecting elements between the two lower beds. Ensure all parts are stored safely if not in use.

6. Maintenance and Care
Proper care will help maintain the appearance and structural integrity of your bunk bed.
- Cleaning: Wipe the metal surfaces with a dry cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish.
- Fastener Checks: Periodically (e.g., every 3-6 months) inspect all bolts, screws, and connections to ensure they remain tight. Re-tighten any loose fasteners to maintain stability and safety.
- Avoid Moisture: Keep the bed in a dry environment to prevent rust or damage to the metal.
- Relocation: When moving the bed, lift it rather than dragging it to prevent damage to the frame or flooring.
7. Troubleshooting
If you encounter issues with your DERCASS Metal Triple Bunk Bed, refer to the following common solutions:
- Missing Parts or Hardware: If you find that parts or hardware are missing upon delivery, immediately contact DERCASS customer support with your purchase details. Do not attempt to substitute parts.
- Bed Wobbles or is Unstable: This is typically caused by loose fasteners. Ensure all bolts and screws are securely tightened. Check that the bed is placed on a level surface.
- Difficulty Assembling: Review the assembly manual carefully, ensuring each step is followed in sequence. Verify that you are using the correct hardware for each connection. Sometimes, parts may appear similar but are designed for specific locations.
- Squeaking Noises: Squeaking can often be resolved by re-tightening all fasteners. Applying a small amount of lubricant (e.g., silicone spray) to connection points can also help, but ensure it is safe for metal and does not leave residue.
