Assembly Instructions
Step-by-Step Guide
Assembly typically takes less than an hour. It is recommended to assemble the foundation in the room where it will be used.
- Unpack Components: Carefully remove all parts from the packaging and lay them out on a clean, soft surface (e.g., carpet or a blanket) to prevent scratching.
- Assemble Frame Sections: Follow the visual instructions provided in your package to connect the main steel frame sections. Ensure all connections are aligned correctly.
- Secure Connections: Use the provided Allen wrench to tighten all bolts and nuts. Do not overtighten initially; hand-tighten all connections first, then fully tighten once the frame is assembled.
- Install Bamboo Slats: Insert the bamboo slats into the designated slots on the steel frame. Ensure each slat is fully seated and secure. Some slats may have anti-slip tape to prevent mattress movement.
- Final Tightening: Double-check all bolts and connections to ensure they are fully tightened for stability and safety.

Usage Guidelines
Placing Your Mattress
The ZINUS SmartBase Essential Mattress Foundation is designed to support various mattress types, including spring, memory foam, and hybrid, without the need for a box spring.
Carefully place your mattress directly onto the bamboo slats. The slats provide even support, promoting mattress longevity and comfort.
Utilizing Underbed Storage
This foundation offers approximately 13 inches of clearance space beneath the frame, ideal for storage. Use storage bins or containers to keep items organized and out of sight.

Care and Maintenance
Routine Care
- Cleaning: Wipe the steel frame with a damp cloth and mild detergent as needed. The bamboo slats can be cleaned with a dry or slightly damp cloth. Avoid harsh chemicals.
- Inspection: Periodically check all bolts and connections to ensure they remain tight. Re-tighten if necessary to maintain stability and prevent squeaking.
- Ventilation: Ensure adequate airflow around and under your mattress to prevent moisture buildup.
Troubleshooting
Common Issues and Solutions
Squeaking Noises:
- Ensure all bolts are securely tightened. Loose connections are a common cause of squeaks.
- Verify that the bamboo slats are properly seated in their respective holders.
- The frame is engineered for silence, but environmental factors or uneven surfaces can sometimes contribute to noise.

Instability:
- Confirm the foundation is placed on a flat, level floor.
- Check that all frame sections are correctly interlocked and secured.
Mattress Slippage:
- Some bamboo slats include anti-slip tape. Ensure your mattress is centered on the foundation. If slippage persists, consider using a non-slip mattress pad.
