Step-by-Step Assembly
- Unpack and Identify Parts: Carefully remove all components from the packaging. Lay them out on a clean, flat surface to identify each part according to the instruction manual.

Maintenance and Care
To maintain the appearance and integrity of your ZINUS Upholstered Metal and Wood Box Spring, follow these simple care instructions:
- Cleaning: Wipe the fabric and metal surfaces with a dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners, as these may damage the finish or fabric.
- Spills: In case of spills, blot immediately with a clean, dry cloth. Do not rub, as this can spread the stain. For stubborn stains, consult a professional upholstery cleaner.
- Inspection: Periodically check all bolts and connections to ensure they remain tight. Re-tighten if necessary to maintain stability.
Troubleshooting
If you encounter any issues with your ZINUS Upholstered Metal and Wood Box Spring, consider the following common solutions:
- Squeaking or Noise: If the box spring produces noise, ensure all assembly bolts are fully tightened. Loose connections are a common cause of squeaking. Verify that the box spring is placed on a stable, level bed frame.
- Instability or Wobbling: Check that the box spring is correctly seated within your bed frame. If your bed frame lacks a lip or sufficient support, the box spring may shift. Ensure all frame components are securely connected.
- Fabric Fit Issues: While the fabric cover is designed for a snug fit, some users may find it challenging to pull into place. Ensure the frame is correctly assembled and square before attempting to fully secure the fabric. Gentle stretching may be required.
- Mattress Sagging: If your mattress appears to sag, first check the condition of the mattress itself. Then, inspect the box spring's wooden slats for any damage or displacement. Ensure they are evenly spaced and properly secured.
If these steps do not resolve the issue, please refer to the Warranty and Support section for further assistance.
