Setup and Assembly
The RuiSiSi L-Shaped Platform Bed Frame requires assembly. A comprehensive, step-by-step instruction manual is included in your package. Please follow these instructions carefully to ensure correct and safe assembly.
- Unpack Components: Carefully remove all parts from the packaging and lay them out on a clean, soft surface to prevent scratches. Verify all parts against the included parts list.
- Assemble Bed Frames: Follow the instructions to assemble the two main twin bed frames, attaching side rails, headboards, and footboards.
- Install Slats: Securely attach the wooden slats to the bed frames. These slats provide mattress support and eliminate the need for a box spring.
- Assemble Built-in Desk: Construct the central built-in desk unit according to the diagrams.
- Assemble Trundle Bed: Assemble the trundle bed frame, ensuring the wheels are properly installed for smooth operation.
- Assemble Storage Drawers: Construct the two storage drawers and install them into the designated slots beneath the bed frame.
- Connect Units: Join the assembled bed frames and desk unit to form the L-shape, ensuring all connections are tight and secure.
It is recommended to have two adults for assembly. Do not overtighten screws, but ensure all connections are firm.

Operating Instructions
This L-shaped bed frame offers multiple functionalities for sleeping and storage.
- Using the Trundle Bed: The trundle bed is located beneath one of the twin beds. Gently pull the trundle frame outwards from the main bed frame until it is fully extended. To retract, push it back into place until it is flush with the main frame. Ensure the trundle wheels are clear of obstructions.
- Utilizing Storage Drawers: The two storage drawers are positioned beneath the other twin bed. Pull the drawers outwards to access storage space for bedding, toys, or other items. Push them back in until they are fully closed. The drawers are convertible and can be placed on either the left or right side during assembly.
- Built-in Desk: The central unit functions as a built-in desk or nightstand. It provides a stable surface for lamps, books, or personal items.

Maintenance
Proper care and maintenance will extend the life of your RuiSiSi bed frame.
- Cleaning: Wipe the wood surfaces with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish.
- Dusting: Regularly dust the bed frame with a dry, soft cloth to prevent buildup.
- Hardware Check: Periodically (e.g., every 3-6 months) inspect all bolts, screws, and connections to ensure they are tight. Retighten if necessary to maintain stability and prevent squeaking.
- Avoid Excessive Moisture: Protect the wood from prolonged exposure to moisture or direct sunlight, which can cause warping or fading.
Troubleshooting
If you encounter any issues with your bed frame, refer to the following common solutions:
- Squeaking Noises: Squeaking often indicates loose hardware. Check and tighten all bolts and screws on the bed frame, especially where the side rails connect to the headboard and footboard, and the slat supports.
- Trundle/Drawers Sticking: Ensure the trundle and drawers are properly aligned on their tracks or wheels. Check for any obstructions beneath or around them. Clean any debris from the tracks.
- Instability/Wobbling: This is typically due to loose connections. Re-check all assembly points and tighten all hardware. Ensure the bed frame is placed on a level surface.
- Missing Parts: If you discover missing parts during assembly, do not proceed. Contact customer support immediately for assistance.
