Setup and Assembly Instructions
Assembly of this bunk bed requires two adults. Please follow the step-by-step instructions provided in the separate assembly diagram and hardware pack. Ensure you have ample space for assembly and keep all small parts out of reach of children.
- Unpack and Identify Parts: Carefully unpack all components and lay them out on a soft, clean surface to prevent scratches. Refer to the parts list in your assembly diagram to identify each piece.
- Assemble Base Frames: Begin by assembling the headboards and footboards for both the twin and full beds, attaching the side rails as instructed.
- Install Slats: Securely attach the wooden slats to the bed frames. Ensure even spacing and firm attachment for proper mattress support.
- Assemble Stairway Unit: Construct the stairway unit, ensuring all storage shelves are correctly positioned and secured.
- Attach Stairway to Bed Frame: Connect the assembled stairway unit to the full-size bed frame as per the instructions.
- Position Upper Bunk: Carefully lift and place the twin-size bed frame onto the full-size bed frame, aligning the connection points. Secure with the specified hardware.
- Install Guardrails: Attach the guardrails to the upper bunk, ensuring they are firmly secured to prevent accidental falls.
- Final Checks: Once assembled, double-check all bolts, screws, and connections to ensure they are tight and secure. Do not overtighten.

Operating Instructions
Using your Merax bunk bed is straightforward once assembled correctly.

- Storage Use: The stairway unit features four integrated storage shelves. These can be used to store books, toys, or other small items, helping to keep the bedroom tidy.
- Mattress Placement: Place your twin mattress on the upper bunk and your full mattress on the lower bunk directly onto the wooden slats. No box spring is required for either bed.

Maintenance and Care
Regular maintenance will help preserve the appearance and structural integrity of your bunk bed.
- Cleaning: Wipe the wood surfaces with a soft, dry cloth. Avoid using harsh chemicals, abrasive cleaners, or excessive moisture, as these can damage the finish.
- Hardware Check: Periodically (e.g., every 3-6 months) inspect all bolts, screws, and fasteners. Tighten any that have become loose to ensure the bed remains stable and safe. Do not overtighten.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause wood finishes to fade or crack. Position the bed away from direct sunlight if possible.
- Humidity Control: Maintain a consistent humidity level in the room to prevent wood from expanding or contracting excessively, which can lead to cracking or warping.
