Setup and Assembly
This box spring is designed for easy assembly. It is recommended to have two people for optimal assembly, though it can be completed by one person. An electric drill can speed up the process, but the included tools are sufficient.
Step 1: Unpack and Identify Parts
Carefully unpack all components from the box. Lay them out on a clean, soft surface. Refer to the included parts list in the manual to identify each piece. The main frame sections are typically labeled 'A' and 'D'.

Step 2: Assemble the Outer Frame
Connect the 'A' and 'D' frame sections using the provided bolts and nuts. Ensure the slat holes on the frame sections are facing upwards. Tighten all connections securely using the wrench or an electric drill. The nuts come with anti-loosening rubber rings, requiring firm tightening.

Step 3: Insert the Slats
Once the outer frame is assembled and tightened, insert the metal slats into the designated slat holes. Press down firmly on both sides of each slat to ensure it is securely seated. The slats provide crucial support for your mattress.

Step 4: Apply the Fabric Cover
Unfold the fabric cover and place it over the assembled metal frame. The cover is designed to fit like a fitted sheet. Pull the elasticized corners over each corner of the frame, ensuring a snug fit. This cover helps to keep the box spring from slipping and provides a clean aesthetic.

Operating Instructions
Once assembled, place the box spring onto your existing bed frame. Ensure it is centered and stable. Then, carefully place your mattress on top of the box spring. The low-profile design provides a subtle lift, and the sturdy metal construction ensures even support for various mattress types, including memory foam and hybrid mattresses.

Maintenance
- Cleaning the Fabric Cover: The fabric cover is removable for spot cleaning. Gently wipe any spills or stains with a damp cloth and mild detergent. Allow to air dry completely before re-applying.
- Frame Care: The metal frame can be wiped clean with a damp cloth. Avoid using harsh chemicals or abrasive cleaners that could damage the finish.
- Regular Checks: Periodically inspect all bolts and connections to ensure they remain tight. Re-tighten if any looseness is detected to maintain stability and prevent noise.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Squeaking noises | Loose bolts or connections. | Check all bolts and nuts and tighten them securely. Ensure slats are properly seated. |
| Mattress sagging | Improperly installed slats or excessive weight. | Verify all slats are correctly inserted and firmly pressed down. Ensure the combined weight of the mattress and occupants does not exceed 3000 lbs. |
| Cover slipping | Cover not properly secured. | Ensure all four elasticized corners of the fabric cover are fully tucked under the box spring frame. |
