Operating Instructions
Using your Merax bunk bed is straightforward. Observe the following for optimal use:

- Staircase Use: Always use the integrated staircase for safe access to and from the upper bunk.
- Storage: Utilize the storage compartments within the staircase for organizing items such as books, toys, or bedding.
- Weight Distribution: Distribute weight evenly on both bunks. Avoid concentrating heavy loads in one area.


Maintenance
Proper maintenance will extend the life of your bunk bed:
- Cleaning: Wipe surfaces with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the finish.
- Hardware Checks: Periodically inspect all bolts, screws, and connections. Tighten any loose hardware to maintain structural integrity.

If you encounter any issues, refer to these common solutions:
- Bed feels wobbly: Check all assembly hardware. Ensure every bolt and screw is securely tightened.
- Parts missing: Refer to your physical parts list. If parts are missing upon delivery, contact Merax customer support immediately.
