3. Slat Installation
Once the main frame is assembled, insert the metal slats into the designated slots along the frame. Ensure each slat is firmly seated to provide even support for your mattress.
4. Cover Installation
Place the poly jacquard cover over the assembled metal frame. The cover is designed to fit snugly, similar to a fitted sheet. Align the corners and pull the cover down over the frame until it is smooth and taut.

Usage and Care
Proper Mattress Placement
Place your mattress directly on top of the assembled and covered box spring. Ensure the mattress is centered and evenly distributed across the surface of the box spring for optimal support and longevity.

Cleaning the Cover
The poly jacquard cover can be spot cleaned as needed. For best results, use a mild detergent and a damp cloth to gently clean any soiled areas. Allow to air dry completely before replacing the mattress.
Troubleshooting
Squeaking Noises
The ZINUS WonderBox Smart Box Spring is designed to be squeak-resistant. If you experience any squeaking, check all frame connections to ensure they are fully engaged and secure. Re-tighten any bolts if applicable, or re-snap any loose connections.
Mattress Sagging
Ensure your mattress is compatible with a box spring foundation. While the WonderBox provides solid support, excessive mattress sagging may indicate an issue with the mattress itself or improper weight distribution. Verify the box spring is placed on a suitable bed frame or platform bed (sold separately).
