3. Setup and Assembly
Assembly of the Merax Daybed requires two adults. Ensure all components are present before beginning. Tools for assembly are provided.
3.1. Unpacking and Component Check
- Carefully unpack all components from the packaging.
- Verify that all hardware components and frame parts are present according to the included parts list. Contact customer support if any parts are missing or damaged.
3.2. Frame Assembly
- Begin by assembling the main daybed frame, connecting the backrest and armrests to the side rails using the provided hardware. Do not fully tighten bolts until all parts are aligned.
- Attach the support legs to the frame.
- Insert the wooden slats into the designated slots on the main daybed frame. Ensure they are evenly spaced and secured.

3.3. Trundle Assembly

- Place the trundle slats onto the trundle frame.
- Once the main daybed frame is mostly assembled, slide the trundle unit into its position underneath the main bed.

3.4. Final Tightening
- Once all components are in place and aligned, fully tighten all bolts and screws using the provided tools. Do not overtighten.
- Place your twin-size mattress on the main daybed frame and, if desired, another twin-size mattress on the trundle.
4. Operating the Pop-Up Trundle
The integrated pop-up trundle allows for easy conversion from a single twin bed to an expanded sleeping area, effectively creating an irregular King size sleeping surface when both are used side-by-side.
4.1. Extending the Trundle
- Locate the fabric pull handle on the front of the trundle unit.
- Gently pull the trundle unit out from underneath the main daybed until it is fully extended.
- Once fully extended, lift the trundle frame upwards. The spring mechanism will assist in raising it to the height of the main daybed. Ensure the locking mechanisms engage securely.

4.2. Retracting the Trundle
- To lower the trundle, disengage the locking mechanisms (usually by pressing a lever or button on the trundle frame).
- Gently push the trundle frame downwards until it is fully lowered.
- Push the trundle unit back underneath the main daybed until it is fully stored.

5. Maintenance
Proper care will extend the life and appearance of your Merax Daybed.
5.1. Upholstery Care (Velvet)
- Regular Cleaning: Vacuum the velvet upholstery regularly using a soft brush attachment to remove dust and debris.
- Spot Cleaning: For spills, blot immediately with a clean, dry cloth. Do not rub, as this can damage the pile. For stubborn stains, use a mild upholstery cleaner, testing on an inconspicuous area first. Follow the cleaner's instructions carefully.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fading. Position the daybed away from direct sun or use curtains/blinds.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, bleach, or harsh solvents, as these can damage the velvet fabric.
5.2. Frame and Hardware Care
- Periodic Inspection: Periodically check all bolts, screws, and connections to ensure they remain tight. Re-tighten as needed to maintain stability.
- Cleaning Frame: Wipe down non-upholstered parts of the frame with a soft, damp cloth. Avoid excessive moisture.
- Lubrication: If the trundle mechanism becomes stiff, a small amount of silicone-based lubricant can be applied to the moving parts, avoiding contact with upholstery.
6. Troubleshooting
If you encounter issues with your Merax Daybed, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Daybed feels unstable or wobbly. | Loose bolts or screws. Uneven floor. | Check and tighten all assembly hardware. Ensure the daybed is on a level surface; use furniture pads if necessary. |
| Trundle is difficult to pull out or push in. | Obstruction. Wheels are dirty or damaged. Mechanism needs lubrication. | Check for any objects blocking the trundle's path. Clean wheels. Apply a silicone-based lubricant to the trundle's sliding mechanism. |
| Trundle does not pop up or lock into place. | Locking mechanism not fully engaged. Spring mechanism issue. | Ensure the trundle is pulled out completely before attempting to lift. Check for any obstructions preventing the mechanism from engaging. If the spring mechanism is faulty, contact customer support. |
