1. Introduction
Thank you for choosing the DEWINNER Bed Base. This manual provides essential information for the safe assembly, operation, and maintenance of your new bed base. Please read these instructions carefully before beginning assembly and keep them for future reference.
The DEWINNER 160x200cm bed base features a reinforced structure with 9 support points, including 4 wooden legs (15cm) and 5 metal legs (25cm), ensuring exceptional stability for heavy loads and frequent movement. Its optimized 25cm height provides generous space underneath for storage or robot vacuum access, while raised legs protect your mattress from humidity and facilitate cleaning. The bed base is equipped with 28 ergonomic poplar slats (2x14 arrangement) for perfect weight distribution, eliminating pressure points and offering optimal lumbar support for restorative sleep. The practical white Jacquard cover is made from high-end, stain-resistant, and breathable fabric, and is removable for easy professional dry cleaning.

4. Setup and Assembly
Assembly typically requires two adults and takes approximately 60-90 minutes. Follow these steps carefully:
- Unpack Components: Lay out all parts on a clean, soft surface (like a carpet) to prevent scratches. Identify each component using the package contents list.
- Assemble the Frame: Connect the main frame sections according to the diagrams provided in your specific assembly guide (not included here, refer to the physical manual). Ensure all connections are secure.
- Attach Legs: Securely attach the 4 wooden legs (15cm) to the corners of the frame. Then, attach the 5 metal legs (25cm) to their designated central and lateral support points. Ensure the 2 central adjustable legs are properly positioned and adjusted for even support.
- Install Slats: Insert the 28 poplar slats into their designated holders on the frame. Ensure they are evenly spaced and securely seated to provide optimal mattress support. The arrangement is 2x14 slats.
- Apply Fabric Cover: Carefully stretch the white Jacquard fabric cover over the assembled bed base. Ensure it fits snugly and covers all sides. Secure it using any integrated fasteners (e.g., Velcro) if present.
- Final Check: Before placing your mattress, double-check all screws and connections to ensure they are tight and the bed base is stable.

5. Usage and Operation
Once assembled, the DEWINNER Bed Base is designed to provide stable and comfortable support for your mattress. Simply place your mattress directly onto the slats. The reinforced structure and ergonomic slats work together to distribute weight evenly, providing optimal support and enhancing the lifespan of your mattress.

6. Maintenance
Proper maintenance will extend the life of your DEWINNER Bed Base:
- Cleaning the Frame: Wipe the frame with a dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
- Cleaning the Fabric Cover: The white Jacquard fabric cover is removable for easy cleaning. For best results, remove the cover and have it professionally dry cleaned. Do not machine wash or tumble dry, as this may damage the fabric or affect its fit.
- Regular Checks: Periodically check all screws, bolts, and leg connections to ensure they remain tight. Re-tighten if necessary to maintain stability and prevent squeaking.
- Under-bed Space: Utilize the generous 25cm under-bed clearance for storage. Keep the area clean to prevent dust accumulation.

7. Troubleshooting
If you encounter any issues with your DEWINNER Bed Base, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Bed base is wobbly or unstable. | Loose screws or uneven leg adjustment. | Ensure all assembly hardware is securely tightened. Adjust the central adjustable legs to ensure even contact with the floor. |
| Squeaking noises. | Loose connections or friction between components. | Re-tighten all screws and bolts. Ensure slats are properly seated. If persistent, apply a small amount of lubricant (e.g., silicone spray) to contact points between slats and frame. |
| Fabric cover does not fit properly. | Incorrect positioning or manufacturing variation. | Ensure the cover is oriented correctly and stretched evenly over the frame. If the issue persists, contact customer support. |
| Bed base sags or feels unsupported. | Exceeded weight capacity or damaged slats. | Verify that the total weight on the bed base (including mattress and occupants) does not exceed 150 kg. Inspect slats for damage and replace if necessary. |
