2. Safety Information
- Always follow the assembly instructions carefully.
- Ensure all bolts and screws are securely tightened before use. Periodically check and re-tighten as necessary.
- Do not exceed the maximum load capacity of 300 kg.
- Keep small parts and packaging materials away from children to prevent choking hazards.
- Avoid jumping on the bed frame.
- If moving the bed frame, lift it rather than dragging to prevent damage to the frame or floor.
3. Product Overview
The HUANUO Single Bed Frame is designed for stability, comfort, and practicality. Key features include:
- High Load Capacity & Stable Design: Constructed from high-strength steel with a powder-coated finish and MDF wood grain boards. Features 15 steel slats and 6 support legs with longitudinal reinforcement bars, supporting up to 300 kg.
- Silent & Anti-Slip Design: U-shaped frame structure with central connection plates and fixing hardware ensures stability. Anti-slip caps on the legs protect floors and reduce noise. Lock-type slat structure prevents lateral movement, and an embedded mattress design prevents mattress shifting.
- Integrated Headboard & Ample Storage: A wood-grain headboard (approx. 12cm deep) provides convenient space for small items like phones, glasses, and alarm clocks. The 30cm under-bed clearance offers significant storage for clothing cases, bedding boxes, and allows for easy cleaning with vacuum cleaners or robotic vacuums.
- Excellent Breathability & Moisture/Mold Resistance: The steel pipe structure promotes airflow, preventing moisture buildup, mold, and dust mites, especially beneficial during humid seasons. The powder-coated steel is rust and moisture-resistant for long-term durability.

4. Setup
Assembly of the HUANUO bed frame is designed to be straightforward. All parts are numbered, and the necessary tools are included. The process typically takes 30-40 minutes.
4.1. Preparation
- Unpack all components and verify against the parts list in the included manual.
- Clear a spacious area for assembly. It is recommended to assemble the bed frame in its final desired location due to its weight once assembled.
- While assembly is possible for one person, having two people is recommended for easier handling and stability during the process.
4.2. Assembly Steps
The assembly is primarily divided into three main steps:

- Frame Construction: Connect the main frame components using the provided bolts and tools. Ensure all connections are aligned.
- Headboard and Footboard Attachment: Secure the headboard and footboard to the main frame.
- Slat Installation: Place and secure the steel slats into the designated slots on the frame.
Important: When tightening bolts, initially hand-tighten all connections. Once all parts are in place and aligned, proceed to fully tighten all bolts, starting from the bottom up, to ensure a stable and squeak-free structure.
5. Operating
5.1. Mattress Placement
Place your single-sized mattress directly onto the installed slats. The bed frame features an embedded design that helps prevent the mattress from slipping or shifting during use, ensuring a stable sleeping surface.
5.2. Headboard Functionality
The integrated wood-grain headboard serves as a convenient shelf. Use it to place small personal items such as your smartphone, glasses, alarm clock, or a book, keeping them within easy reach.

5.3. Under-Bed Storage
Utilize the generous 30cm clearance beneath the bed frame for storage. This space is ideal for storing seasonal clothing, extra bedding, or other items in storage boxes, helping to maximize space in smaller rooms.

6. Maintenance
- Cleaning: Wipe the steel frame and MDF panels with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Ventilation: The bed frame's design promotes air circulation. Ensure adequate room ventilation to further enhance mattress longevity and prevent moisture buildup.
- Fastener Check: Periodically inspect all bolts and connections to ensure they remain tight. Re-tighten any loose fasteners to maintain stability and prevent squeaking.
- Floor Protection: The bed legs are equipped with anti-slip caps. To further protect delicate flooring, consider placing additional felt pads or floor protectors under each leg.

7. Troubleshooting
- Squeaking or Shaking: If the bed frame makes noise or feels unstable, re-check all assembly points. Ensure all bolts are fully tightened. The U-shaped frame and lock-type slat structure are designed to minimize noise and movement.
- Mattress Fit Issues: If your mattress feels too snug or does not fit perfectly, verify its dimensions against the bed frame's internal dimensions (97cm width x 195cm length). Some mattress covers or thicker mattresses might reduce available space.
- Floor Scratches: Although the bed legs have protective caps, if you notice floor marks, consider adding additional, softer floor protectors under each leg, especially on delicate surfaces.
