Assembly Instructions
The ZINUS Smart Box Spring features a quick and intuitive assembly process with tool-free locking brackets and a push-pin system. Assembly typically takes minutes to complete.
- Unpack Components: Carefully remove all parts from the packaging. Lay them out on a clean, flat surface to identify each piece.
- Connect Frame Sections: Begin by connecting the main steel frame sections. The design utilizes a push-pin system where one end of a bar slides into another, and a pin locks it in place. No tools are required for these connections.

- Install Locking Brackets: Attach the tool-free locking brackets to the designated points on the frame. These brackets slide into place and secure the frame without the need for additional bolts.

- Complete Frame Assembly: Continue connecting all frame pieces and securing them with the locking brackets until the full metal frame is rigid and complete. Ensure all connections are firm.
- Apply Fabric Cover: Once the frame is fully assembled, carefully place the poly jacquard cover over the frame. The elastic band ensures an easy and snug fit, similar to a fitted sheet.

Maintenance
- Cleaning: Wipe the steel frame with a dry cloth as needed. The poly jacquard cover can be spot cleaned with a mild detergent and damp cloth. Do not machine wash or tumble dry the cover.
- Inspection: Periodically inspect all frame connections and locking brackets to ensure they remain secure. Re-tighten any loose connections if necessary.
- Avoid Moisture: Keep the box spring in a dry environment to prevent rust or damage to the materials.
Troubleshooting
Squeaking Noises
- Cause: Loose connections in the frame or friction between the box spring and bed frame.
- Solution: Re-check all push-pin connections and locking brackets to ensure they are fully engaged. If the noise persists, ensure the box spring is properly seated on your bed frame and that the bed frame itself is stable.
Instability or Wobbling
- Cause: Incomplete assembly or uneven placement on the bed frame.
- Solution: Verify that all frame components are correctly assembled and locked into place. Ensure the box spring is placed on a flat, level bed frame.
