Step 1: Assemble Headboard and Footboard Units
Begin by assembling the headboard and footboard units. Connect the Headboard/Footboard Upper Horizontal Bar (Part 3) and Headboard/Footboard Lower Horizontal Bar (Part 6) between the Headboard/Footboard Outer Vertical Posts (Part 1) and Headboard/Footboard Inner Vertical Posts (Part 2). Secure these connections using M6x30mm Bolts (Hardware B) and M6 Washers (Hardware F). Then, insert the Headboard/Footboard Decorative Panel (Part 7) into the designated slots on the assembled frame. Repeat this process for the second unit.

Step 2: Assemble Side Rails with Center Support Legs
Attach the Center Support Legs (Part 4) to the Side Rails (Part 5) using M6x15mm Bolts (Hardware C) and M6 Washers (Hardware F). Ensure the legs are firmly attached and perpendicular to the side rails for proper support.

L-shaped brackets reinforce the joints for enhanced stability and durability.
Step 3: Connect Headboard/Footboard to Side Rails
Connect the assembled headboard and footboard units to the Side Rails (Part 5) using M8x50mm Bolts (Hardware A) and M8 Washers (Hardware E). Tighten all connections securely with the provided Allen wrench and small wrench (Hardware G). Ensure all connections are snug to prevent wobbling.

Step 4: Install Bed Slats
Place the Bed Slats (Part 9) across the Side Rails (Part 5). Secure each slat to the frame using M4x10mm Screws (Hardware D). Ensure even spacing for optimal mattress support. The built-in slats are designed to prevent mattress sliding.

The integrated slat design helps keep your mattress securely in place, preventing unwanted movement.

Operating Instructions
Once assembled, place your mattress directly onto the bed slats. No box spring is needed for this platform bed frame. The frame is designed to support a mattress of 75" L × 39" W. Ensure the mattress is centered on the frame for even weight distribution and stability.

The 12.6-inch ground clearance provides ample space for under-bed storage solutions.
Maintenance
To maintain your Yaheetech Metal Platform Bed Frame, regularly wipe clean with a dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners, as these may damage the powder-coated finish. Periodically check all bolts and connections to ensure they remain tight. Re-tighten if any looseness is detected to maintain structural integrity and prevent squeaking.
Troubleshooting
- Squeaking Noises: If the bed frame produces squeaking noises, it is likely due to loose connections. Re-tighten all bolts and screws, especially those connecting the side rails to the headboard/footboard and the center support legs.
- Mattress Sliding: While the frame has built-in features to minimize sliding, some mattresses may still shift. Consider using a non-slip mattress pad or rubber grippers placed between the mattress and the slats to further secure it.
- Wobbly Frame: A wobbly frame indicates loose connections. Systematically check and tighten every bolt and screw on the entire frame. Ensure the center support legs are properly aligned and secured.
- Missing Parts: If any parts are missing upon unboxing, please contact Yaheetech customer support immediately for assistance.
