Important Safety Information
Please read and understand all instructions before assembly and use. Failure to follow these instructions may result in injury or damage to the product.
- Pinch Points: Be cautious of pinch points during assembly. Keep hands and fingers clear of moving parts and connection points.
- Weight Capacity: Do not exceed the maximum weight capacity of 350 lbs for Twin/Twin XL sizes. Full, Queen & King sizes can support up to 700 lbs. Overloading can compromise the structural integrity and lead to collapse.
- Assembly: Always follow assembly instructions carefully to prevent instability. Ensure all connections are secure before use.
- Bed Frame Requirement: This product is a box spring only. A separate bed frame or platform bed is required to support this foundation and is sold separately. Do not use this box spring without a proper supporting bed frame.

Operating (Usage Guidelines)
The ZINUS 5 Inch Metal Smart Box Spring is designed for straightforward use as a mattress foundation. To ensure optimal performance and longevity:
- Mattress Placement: Always place your mattress directly on top of the box spring. Ensure the mattress is centered and fully supported by the box spring's surface.
- Even Weight Distribution: Avoid concentrating heavy loads or standing on specific small areas of the box spring. Distribute weight as evenly as possible.
- Ventilation: Ensure adequate air circulation around and under the box spring to prevent moisture buildup, especially if placed on a solid platform bed.
Maintenance
Proper care and maintenance will help extend the life of your ZINUS Smart Box Spring:
- Cleaning: To clean the poly jacquard cover, wipe with a dry cloth. For tougher spots, a slightly damp cloth with mild soap can be used, but ensure it dries completely to prevent mildew.
- Frame Inspection: Periodically inspect the steel frame and all connections to ensure they remain tight and secure. Re-tighten any loose connections if necessary.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or harsh chemicals on the frame or cover, as this may damage the materials.
Troubleshooting
If you encounter any issues with your ZINUS Smart Box Spring, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Squeaking Noise | Loose connections in the frame. | Check all frame connections and ensure they are fully engaged and secure. If applicable, re-tighten any bolts (though this model is tool-free, ensure push-pins are fully seated). |
| Instability/Wobbling | Improper assembly or uneven placement on bed frame. | Verify that all frame pieces are correctly assembled and locked. Ensure the box spring is placed on a flat, stable bed frame. |
| Cover does not fit snugly | Cover not properly aligned or stretched. | Remove the cover and re-apply, ensuring the elastic band is evenly distributed around the base of the box spring. |
If the issue persists after attempting these solutions, please contact ZINUS customer support for further assistance.
