4. Operating Instructions
The GAOMON Twin Day Bed with Trundle is designed for versatile use as a sofa or an extra sleeping space.
- Using the Main Daybed: Place a twin-size mattress (6-8 inches thick recommended) on the main bed slats. The daybed can function as a sofa during the day.
- Using the Pull-Out Trundle: To use the trundle bed, gently pull it out from under the main daybed. The universal casters allow for smooth movement. Place a twin-size mattress (up to 6 inches thick recommended) on the trundle slats.
- Storing the Trundle: When not in use, push the trundle bed back under the main daybed. Ensure it is fully retracted to save space.

5. Maintenance
Regular maintenance will help prolong the life of your daybed.
- Cleaning: Wipe down the metal frame with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners that could damage the finish.
- Fasteners: Periodically check all bolts and screws to ensure they remain tight. Re-tighten as necessary to maintain stability and prevent squeaking.
- Casters: Keep the trundle casters free of debris to ensure smooth operation.
6. Troubleshooting
If you encounter any issues, refer to the following common solutions:
- Squeaking Noises: Squeaking often indicates loose connections. Check and re-tighten all bolts and screws on both the main bed and the trundle frame. Ensure slats are properly seated in their grooves.
- Trundle Not Moving Smoothly: Check the universal casters for any obstructions (e.g., carpet fibers, dust). Clean the casters if necessary. Ensure the floor surface is clear.
- Instability: If the bed feels unstable, verify that all assembly steps have been followed correctly and all fasteners are fully tightened. Do not use the bed if it feels unstable.
