3. Assembly Instructions
Assembly typically requires two adults and takes approximately 30-60 minutes. Follow these general steps:
- Unpack Components: Carefully remove all parts from the packaging and lay them out on a clean, soft surface (e.g., carpet) to prevent scratches. Identify each part using the provided labels.
- Assemble Frame Sections: Connect the head and foot sections to the side rails using the provided bolts and the Allen wrench. Do not fully tighten bolts until all sections are aligned.
- Attach Center Supports: Secure the center support beams to the frame. Ensure they are properly aligned with the pre-drilled holes.
- Install Legs: Attach all support legs to the designated points on the frame. Some legs may have adjustable height features; ensure they are set to the desired height before final tightening.
- Place Slats: Lay the metal support slats across the frame. Ensure they are evenly spaced and securely fastened, if applicable, to prevent movement and noise.
- Final Tightening: Once all components are in place and aligned, systematically tighten all bolts using the Allen wrench. Do not overtighten.
- Position Frame: Carefully move the assembled bed frame to its desired location.

4. Operating Your Bed Frame
The Hafenpo 18 Inch King Metal Platform Bed Frame is designed for use with a King size mattress without the need for a box spring.
- Mattress Placement: Carefully place your King size mattress directly onto the metal slats. Ensure the mattress is centered and fully supported by the frame.
- Weight Capacity: The bed frame is designed to support a maximum weight of 1100 pounds, including the mattress and occupants. Do not exceed this limit.
- Under-Bed Storage: The 18-inch height provides approximately 16.1 inches of clearance for under-bed storage, allowing you to maximize space in your room.

5. Maintenance
Regular maintenance helps ensure the longevity and stability of your bed frame.
- Cleaning: Wipe the metal frame with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the powder-coated finish.
- Check Connections: Periodically (e.g., every 3-6 months) inspect all bolts and connections. Tighten any that have become loose to prevent squeaking and maintain stability.
- Noise Prevention: The frame features a noise-free design. If squeaking occurs, re-check all connections and ensure the mattress is properly seated.
