- Assemble the Footboard: Connect the footboard components in the same manner as the headboard.
- Attach Side Rails: Connect the side rails to the assembled headboard and footboard using the appropriate bolts.
- Install Center Support: Place the center support beams and legs into position and secure them.
- Place Metal Slats: Lay the metal slats across the frame. The slats are designed to fit securely into the frame, providing a stable base for your mattress.

Operating Instructions
- Mattress Placement: Carefully place your full-size mattress directly onto the metal slats. No box spring is needed.
- Weight Capacity: The bed frame is designed to support a standard full-size mattress and occupants. Do not exceed the recommended weight capacity to ensure longevity and safety.
- Under-Bed Storage: Utilize the ample 12-inch clearance under the bed for storage. Ensure items stored do not obstruct airflow or put undue pressure on the frame.

Maintenance
- Cleaning: Wipe the metal frame with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the powder-coated finish.
- Tighten Bolts: Periodically (e.g., every 3-6 months) check all bolts and connections and tighten them as needed to maintain stability and prevent squeaking.
- Slat Inspection: Inspect the metal slats for any signs of bending or damage. Replace any damaged slats immediately to ensure proper mattress support.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bed frame is squeaking. | Loose bolts or metal-on-metal friction. | Tighten all bolts. Ensure all slats are properly seated. The frame is designed to be squeak-resistant, but periodic tightening is recommended. |
| Bed frame feels unstable. | Loose connections or uneven floor. | Verify all bolts are fully tightened. Ensure the bed is on a level surface. Adjust leg levelers if applicable (check product for this feature). |
| Mattress is sagging. | Damaged or improperly placed slats. | Check that all metal slats are correctly installed and not bent or damaged. Replace any compromised slats. |
