Operating Instructions
- Mattress Placement: Place a standard twin-size mattress on both the upper and lower bunks. Ensure the mattress on the upper bunk does not exceed the height of the guardrails.

- Weight Distribution: Distribute weight evenly across the bed frames. Avoid concentrating heavy loads in one area.
Maintenance
- Cleaning: Wipe the metal frame with a damp cloth for general cleaning. For stubborn marks, a mild soap solution can be used, followed by wiping with a dry cloth. Avoid abrasive cleaners.
- Hardware Check: Periodically (e.g., every 3-6 months) inspect all bolts, screws, and connections to ensure they remain tight. Retighten as necessary to maintain stability and safety.
- Rust Prevention: The bed frame is coated with a rust-proof finish. To maintain this, avoid prolonged exposure to moisture.
