Setup and Assembly
Assembly of the Yaheetech Sectional Sofa typically requires two people and a drill for certain steps. Follow the included assembly instructions carefully. Below are general steps and important considerations:
- Unpack Components: Carefully remove all parts from the four packages. Verify all components listed in the "Package Contents" section are present.
- Assemble Bases: Connect the main sofa base and the chaise base according to the diagrams in the instruction manual. Ensure all locking brackets slide in correctly. Note: Some users have reported that brackets may require slight adjustment or bending to fit.
- Attach Legs: Securely attach the furniture legs to the bases.
- Install Trundle Bed Rollers: For the pull-out trundle bed, you will need to attach the rollers to the bottom. A drill is required for this step as pre-drilled holes may not be present. Carefully align the rollers and screw them into the wood.
- Attach Armrests: Secure the armrests to the main sofa body. This step may be easier with a second person. Ensure they are firmly attached.
- Place Cushions and Backrests: Position the seat cushions and back pillows. The backrests slide into place.
- Final Check: Before use, double-check all connections and ensure the sofa is stable.

Operating Instructions
Converting to Trundle Bed
The sectional sofa easily converts into a comfortable bed for two. Locate the two straps on the front of the loveseat section. Gently pull these straps to extend the trundle mechanism forward. The hidden bed will pop up and align with the seat cushions, creating a flat sleeping surface.

Utilizing Storage Compartment
The chaise section of the sofa features a spacious hidden storage compartment. To access, lift the seat cushion of the chaise. The lid is designed to stay open, allowing for easy storage and retrieval of items like blankets and pillows.

Maintenance and Care
Proper care will extend the life and appearance of your sofa:
- Cleaning Fabric: The cushion covers can be unzipped and are washable. Refer to the fabric care label for specific washing instructions. For spot cleaning, use a mild detergent and a damp cloth, then blot dry.
- Frame Care: Wipe the metal and wood components with a dry or slightly damp cloth. Avoid harsh chemicals.
- Cushion Fluffing: Regularly fluff and rotate cushions to maintain their shape and even out wear.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fabric fading.
- Weight Distribution: Distribute weight evenly across the sofa to prevent undue stress on any single area.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Difficulty assembling armrests or bases. | Misalignment of locking brackets or components. | Ensure components are correctly oriented. Apply gentle force or slightly adjust/bend brackets if necessary. Assembly with a second person is recommended. |
| Trundle bed rollers cannot be installed. | Lack of pre-drilled holes for rollers. | A drill is required. Carefully align the rollers and use a drill to screw them directly into the wood base. |
| Sofa feels unstable or wobbly. | Loose connections or uneven legs. | Re-tighten all screws and bolts. Ensure legs are securely attached and adjusted if possible to level the sofa on uneven floors. |
| USB ports not charging devices. | Power source issue or faulty connection. | Ensure the sofa's power cable (if applicable) is properly plugged into a working outlet. Check the USB cable and device for functionality. |
