Introduction
The Zinus 7 Inch Twin Metal Smart Box Spring provides a durable and stable foundation for your mattress. Designed for quick and easy assembly, this box spring offers reliable support without the bulk of traditional foundations. Its robust steel frame ensures longevity and consistent mattress performance.
Safety Information
Please read and understand all instructions before assembly and use. Keep small parts away from children. Exercise caution around tool-free locking brackets during assembly to prevent pinching. Do not exceed the maximum weight capacity of 350 lbs for Twin/Twin XL sizes. A bed frame or platform bed is required to support this foundation and is sold separately.
Setup and Assembly
The Zinus Smart Box Spring features a tool-free quick assembly design, allowing for setup in minutes. All necessary parts and instructions are conveniently packed in one compact box.
Assembly Steps:
- Unpack and Organize: Carefully unpack the box and lay out all components on a clean, flat surface. Ensure all parts are present according to the parts list.
- Assemble the Frame: Attach the tool-free locking brackets to the sides of the box spring frame. These brackets are designed for intuitive, quick connection.
- Secure Connections: Align and lock the frame sections together using the push-pin system. Ensure all connections are tight and stable before proceeding.
- Insert Slats: Place the metal slats across the assembled frame. These slats provide robust support for your mattress.
- Apply the Cover: Once the frame is fully assembled and stable, stretch the poly jacquard cover over the metal structure. The elastic band ensures a snug fit.

Operating Instructions
The Zinus Smart Box Spring is designed to provide a stable and even surface for your mattress, enhancing its comfort and longevity.

The sturdy steel construction ensures consistent support across the entire mattress surface.

Maintenance
To maintain the quality and appearance of your Zinus Smart Box Spring, wipe the metal frame with a dry cloth as needed. The poly jacquard cover can be removed for cleaning if necessary, following standard fabric care instructions. Regular inspection of the frame and connections is recommended to ensure continued stability.
Troubleshooting
Common Issues and Solutions:
- Squeaking Noises: If you experience squeaking, re-check all connections and ensure they are securely fastened. Sometimes, slight adjustments can eliminate noise.
- Instability/Wobbling: Verify that the box spring is placed on a flat, even surface and that all frame components are correctly interlocked. Ensure your bed frame or platform bed is also stable.
- Mattress Sagging: While the box spring provides firm support, ensure your mattress itself is not worn out. The box spring is designed to support the mattress, not to correct a sagging mattress.
