- Assemble the main metal frame. The pieces are designed to fit together easily.

Operating Instructions
Once assembled, the ZINUS Keenan Metal Mattress Foundation is ready for immediate use. Simply place your mattress directly on top of the foundation. The sturdy steel slats provide ample support, eliminating the need for a traditional box spring. The integrated design ensures a stable and comfortable sleeping surface.
Maintenance
To maintain the quality and appearance of your ZINUS Keenan Metal Mattress Foundation, simply wipe it with a dry cloth as needed. Avoid using harsh chemicals or abrasive cleaners, which may damage the finish or fabric cover. Periodically check all connections to ensure they remain secure.
Troubleshooting
Squeaking Noises
If you experience squeaking noises, first ensure all bolts and connections are tightened securely. Over time, normal use can cause connections to loosen slightly. Re-tightening all fasteners should resolve most squeaking issues. Verify that the mattress is properly seated on the slats and not shifting.
Instability
If the foundation feels unstable, double-check that all legs are firmly attached and evenly distributed. Ensure the frame is assembled correctly according to the instructions. Uneven flooring can also contribute to perceived instability; consider using furniture pads or shims if necessary.
