1. Introduction
This manual provides essential instructions for the safe assembly, operation, and maintenance of your Merax Full Over Full Metal Bunk Bed. This versatile bed features a durable metal frame, a ladder, and high guardrails, designed to accommodate two full-size mattresses. It can also be split into two individual full-size beds, offering flexibility for your space. Please read all instructions carefully before assembly and use.
2. Safety Information
WARNING: Failure to follow these safety guidelines can result in serious injury.
- Always follow the assembly instructions carefully to ensure the bed frame is stable and secure.
- Be cautious of sharp edges, especially when assembling or disassembling the bed frame.
- Keep the bed frame away from heat sources to prevent warping or damage.
- Do not exceed the maximum weight capacity of 250 pounds on the top bunk and 350 pounds on the bottom bunk.
- Always supervise children when they are using the bed frame.
- Ensure all connections are tight before each use and periodically check for loose hardware.
- The top bunk is not suitable for children under 6 years of age.
- Use only mattresses that are 74-75 inches long and 53-54 inches wide for full-size beds. The maximum mattress thickness for the top bunk should not exceed 6 inches to ensure adequate guardrail height.
3. Setup and Assembly
Your Merax bunk bed is designed for straightforward assembly. It is delivered in one package and includes an installation manual and all necessary hardware. For optimal safety and ease, two people are recommended for assembly.
3.1 Unpacking and Preparation
- Clear a spacious area for assembly.
- Carefully unpack all components and hardware. Verify that all parts are present against the included parts list.
- Keep small parts away from children during assembly.
3.2 Assembly Steps
Follow the detailed, step-by-step instructions provided in the separate installation manual included with your product. Ensure all bolts and screws are tightened securely, but do not overtighten until instructed, to allow for minor adjustments.

Note: Some users have reported minor alignment issues with pre-drilled holes. If encountered, gently adjust components before fully tightening hardware.
4. Operating Instructions
4.1 Using as a Bunk Bed
- Ensure mattresses are properly sized and placed within the bed frame.
- Always use the integrated ladder for accessing the top bunk. Do not climb on the guardrails or frame.
- Periodically check the ladder and guardrail connections for stability.
4.2 Splitting into Two Individual Beds
This bunk bed can be easily separated into two independent full-size beds. Refer to your assembly manual for specific disassembly steps. Generally, this involves carefully unbolting the connecting posts and separating the upper and lower bed frames. Ensure all original hardware is stored safely if you plan to reassemble as a bunk bed later.

5. Maintenance
5.1 Cleaning
For the metal frame, wipe clean with a soft, dry cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish. The product care instructions state "Dry Clean Only"; this typically refers to any fabric components or bedding, not the metal frame itself. For the metal frame, a damp cloth followed by a dry cloth is suitable for general cleaning.
5.2 Regular Checks
- Periodically inspect all bolts, screws, and connections to ensure they remain tight. Retighten as necessary to maintain structural integrity and prevent noise.
- Check the ladder and guardrails for any signs of wear or damage. Replace any damaged parts immediately.
6. Troubleshooting
- Wobbling or Instability: Ensure all assembly hardware is fully tightened. If the bed still wobbles, disassemble and reassemble carefully, ensuring all parts are correctly aligned.
- Noise (Squeaking/Creaking): Check all connections and tighten any loose bolts. Applying a small amount of lubricant (e.g., silicone spray) to metal-on-metal contact points can help reduce noise.
- Guardrail Concerns: If guardrails appear weak or have snapped, discontinue use of the top bunk immediately. This indicates a structural failure and requires replacement parts or professional assessment. Do not attempt to repair compromised safety components yourself.
- Parts Missing or Damaged: If you find any parts missing or damaged upon unpacking, do not proceed with assembly. Contact Merax customer support or your retailer for assistance.
