Assembly Instructions
The ZINUS WonderBox(TM) Smart Box Spring features a quick, tool-free assembly process. Follow these steps for a hassle-free setup:
- Unpack and Lay Out Components: Carefully remove all components from the shipping box. Lay out the metal frame pieces on a clean, flat surface in the room where the box spring will be used. Identify the 'uppers' on the frame pieces, as these are where the slats will sit.
- Assemble the Outer Frame: Connect the outer frame pieces by pushing them together until they snap into place. This design requires no tools. Ensure all connections are secure and the frame forms a stable rectangle.
- Install the Slats: Take each metal slat and align its ends with the designated slots on the assembled outer frame. Push down firmly until each slat clicks securely into place. Ensure all slats are evenly spaced and fully seated for optimal support.
- Apply the Fabric Cover: Once the metal frame is fully assembled, take the poly jacquard fabric cover. It is designed like a fitted sheet. Line up the corners of the cover with the corners of the box spring frame and pull it over, ensuring a snug fit. The cover protects the mattress from dust and stains.
- Final Placement: Place the assembled box spring onto your bed frame or platform bed. Ensure it is centered and stable before placing your mattress on top.

Operating Instructions
The ZINUS WonderBox(TM) Smart Box Spring is designed for passive operation, providing consistent support for your mattress. Proper placement and use are key to maximizing its benefits.
- Placement: Always place the box spring on a sturdy bed frame or platform bed. Ensure the frame is level and capable of supporting the combined weight of the box spring, mattress, and occupants.
- Mattress Compatibility: This box spring is compatible with all mattress types, including memory foam, spring, latex, and hybrid mattresses.
- Weight Distribution: Distribute weight evenly across the mattress and box spring to prevent undue stress on any single point.
Maintenance
Regular maintenance will help prolong the life of your ZINUS WonderBox(TM) Smart Box Spring:
- Cleaning the Cover: The poly jacquard cover can be spot cleaned with a mild detergent and damp cloth. For deeper cleaning, the cover can be removed and hand washed or machine washed on a gentle cycle with cold water. Air dry only. Do not bleach or iron.
- Frame Inspection: Periodically inspect the metal frame for any loose connections or signs of wear. Re-tighten any connections if necessary, although the tool-free design minimizes this need.
- Ventilation: Ensure adequate airflow around the box spring and mattress to prevent moisture buildup.
Troubleshooting
If you encounter any issues with your ZINUS WonderBox(TM) Smart Box Spring, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Squeaking noises | Loose connections or friction between metal parts. | Ensure all frame connections are fully snapped into place. Verify slats are securely seated. If squeaking persists, apply a small amount of lubricant (e.g., silicone spray) to connection points. |
| Box spring feels unstable | Improper assembly or uneven bed frame. | Re-check all assembly steps to ensure components are correctly connected. Verify your bed frame is level and provides adequate support. |
| Cover does not fit properly | Incorrect orientation or not fully stretched. | Ensure the cover is oriented correctly (long sides with long sides, short with short). Stretch the cover firmly over all corners and edges. |
