Assembly Instructions
This Zinus Smart Box Spring features a new quick assembly design with fewer bolts and tool-free locking brackets for a straightforward setup. Assembly typically takes minutes to complete.
- Unpack Components: Carefully remove all parts from the packaging and lay them out on a clean, flat surface. Refer to the included parts list to ensure all pieces are present.
- Assemble Frame Sections: Connect the steel frame sections using the push-pin system. Align the pins with the corresponding holes and push until they click into place. No tools are required for these connections.
- Attach Locking Brackets: Secure the frame corners and central supports using the tool-free locking brackets. These brackets slide into place and lock the frame sections together for added stability.
- Install Support Bars: Place the steel support bars across the frame, ensuring they are evenly spaced and securely seated in their designated slots.
- Apply Cover: Once the frame is fully assembled and stable, stretch the poly jacquard cover over the entire structure. The elastic band ensures a snug fit and is easy to put on and take off.
- Placement: Position the assembled box spring onto your existing bed frame or platform bed.

Maintenance
- Cleaning: The poly jacquard cover can be removed for spot cleaning. For deeper cleaning, follow the care instructions on the cover's label. The steel frame can be wiped clean with a damp cloth.
- Inspection: Periodically check all connections and fasteners to ensure they remain tight and secure. Re-tighten if necessary.
- Weight Distribution: To prolong the life of both your box spring and mattress, ensure weight is distributed evenly across the surface.
Troubleshooting
Squeaking Noises
If you experience squeaking, check the following:
- Ensure all frame connections and locking brackets are fully engaged and secure.
- Verify that the box spring is sitting evenly and stably on your bed frame. Uneven surfaces can cause stress points.
- Check if the mattress itself is causing the noise by removing it and testing the box spring alone.
Instability
If the box spring feels unstable:
- Re-check all assembly steps to ensure correct installation of all frame components and brackets.
- Confirm that the box spring is placed on a sturdy and level bed frame or foundation.
