Assembly is required for this sectional sofa. It is recommended to have two people for assembly. Please follow these steps carefully:
- Prepare the Area: Clear a spacious area for assembly. Lay down a blanket or cardboard to protect your floor and the sofa components.
- Attach Legs: For each sofa section, locate the pre-drilled holes on the underside. Attach the sofa legs using the provided bolts and Allen wrench. Ensure all legs are securely tightened.
- Connect Sofa Sections: Arrange the sofa sections in your desired U-shaped configuration. Use the included connecting brackets (usually located on the underside or sides of the frames) to link the sections together. Slide the brackets into place until they lock securely.
- Place Cushions: Position the seat cushions and back cushions onto the sofa frame. Fluff cushions as needed to restore their shape.
- Final Check: Verify that all connections are secure and the sofa is stable before use.

5. Operating Instructions
5.1 Hidden Storage Chaise Lounges
Your sectional features two spacious hidden storage compartments beneath each chaise lounge. These are ideal for storing blankets, pillows, toys, or other household items.
- To Open: Locate the pull-strap on the front edge of the chaise cushion. Gently pull upwards on the strap to lift the cushion and access the storage compartment.
- To Close: Carefully lower the chaise cushion until it rests securely on the frame. Ensure no items are obstructing the closing mechanism.

5.2 USB Charging Ports
Each armrest of your sectional sofa is equipped with two built-in USB charging ports (four total) for convenient device charging.
- To Use: Connect your device's USB charging cable to one of the available ports. Ensure the sofa is properly plugged into a power outlet (if applicable, check for a power cord from the sofa).
- Note: Charging speed may vary depending on the device and cable used.

5.3 Reconfiguring the Modular Layout
The modular design allows you to adapt the sofa's configuration to suit your space and needs. Both chaise lounges can be placed on either side of the armless sections, or combined to form a larger lounging or sleeping area.
- To Reconfigure: Disconnect the sofa sections by disengaging the connecting brackets on the underside. Rearrange the sections as desired, then reconnect them securely using the brackets.

6. Maintenance and Care
To keep your Lyngins sectional sofa looking its best, follow these care guidelines:
- Regular Cleaning: Vacuum the sofa regularly using an upholstery attachment to remove dust and debris.
- Spot Cleaning: For spills, blot immediately with a clean, dry cloth. For stubborn stains, use a mild fabric cleaner specifically designed for polyester upholstery. Test on an inconspicuous area first.
- Avoid Harsh Chemicals: Do not use harsh detergents, bleach, or abrasive cleaners, as these can damage the fabric.
- Sunlight Exposure: Avoid prolonged exposure to direct sunlight to prevent fading of the fabric.
- Fluff Cushions: Periodically fluff and rotate seat and back cushions to maintain their shape and even out wear.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sofa feels wobbly or unstable. | Legs are loose or not fully tightened. Sections are not securely connected. | Check and tighten all sofa legs. Ensure all connecting brackets between sections are fully engaged. |
| USB ports are not charging devices. | Sofa not plugged into a power source (if applicable). Device cable is faulty. | Verify the sofa's power cord is securely plugged into a working wall outlet. Try a different USB cable or device to rule out cable/device issues. |
| Chaise storage lid does not close properly. | Items inside the storage compartment are obstructing the lid. | Rearrange or remove items from the storage compartment to ensure a clear closing path. |
| Fabric appears wrinkled or creased. | Normal during shipping or initial use. | Allow time for the fabric to relax. Gentle steaming (from a distance) can help, but test on an inconspicuous area first. |
