Assembly Instructions
The HOBINCHE bed frame is designed for simple assembly, typically completed by one person in approximately 20 minutes. Follow these steps carefully:
Step 1: Unpack and Identify Components
Carefully remove all parts from the packaging. Lay them out on a clean, soft surface (like a carpet) to prevent scratches. Identify each part using the provided parts list in your package.
Step 2: Assemble the Main Frame
Connect the side rails and end rails to form the rectangular perimeter of the bed frame. Ensure all connections are aligned before tightening screws. The frame features sturdy central support for enhanced stability.

Step 3: Attach Legs and Slats
Attach the support legs to the frame. The legs are equipped with rubber feet to prevent noise and protect your floor. Insert the metal slats into the designated U-shaped grooves on the frame. These grooves help fix the slats in place, preventing them from sliding.

Operating Instructions
Mattress Placement
This platform bed frame is designed to be used without a box spring. Place your King size mattress directly onto the steel slats. The robust steel slats provide optimal support for your mattress, ensuring comfort and longevity.

Under-Bed Storage
The 12-inch height of the bed frame provides ample clearance for under-bed storage. This space can be utilized for storing items such as suitcases, storage boxes, shoes, or other belongings, helping to maximize space in your bedroom.

Maintenance
To ensure the longevity and optimal performance of your HOBINCHE bed frame, follow these maintenance guidelines:
- Cleaning: Wipe the metal frame with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, which can damage the finish.
- Fastener Check: Periodically (e.g., every 3-6 months) check all screws and bolts to ensure they remain tight. Retighten as necessary to maintain stability and prevent noise.
- Floor Protectors: Ensure the rubber feet on the legs are intact and in place to protect your flooring from scratches and reduce noise. Replace if worn.
Troubleshooting
If you encounter any issues with your bed frame, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Squeaking or Noise | Loose fasteners; uneven floor; worn floor protectors. | Tighten all screws and bolts. Ensure the bed frame is on a level surface. Check and replace worn rubber feet. |
| Frame feels unstable | Loose connections; incorrect assembly. | Review assembly instructions to ensure all parts are correctly installed and all fasteners are fully tightened. |
| Slats sliding out of place | Slats not properly seated in U-shaped grooves. | Ensure each slat is fully inserted and seated within its U-shaped groove on both sides of the frame. |
