- Modular Configuration: Each module can be rearranged to create various seating arrangements, from a single chair to a large sectional. Simply disconnect and reconnect modules using the connecting brackets.

5. Maintenance and Care
Proper care will extend the life of your LINSY HOME Rubik III sofa:
- Removable & Machine-Washable Covers: All sofa covers are designed to be removable and machine-washable. Follow the care instructions on the fabric tag for best results. Typically, wash in cold water on a gentle cycle and tumble dry low.
- Spot Cleaning: For minor spills, blot immediately with a clean, dry cloth. Avoid rubbing, which can spread the stain. Use a mild fabric cleaner if necessary, testing on an inconspicuous area first.
- General Cleaning: Vacuum regularly using an upholstery attachment to remove dust and debris.
- Cushion Care: Rotate and fluff cushions periodically to maintain their shape and even out wear.

6. Troubleshooting
If you encounter any issues with your sofa, consider the following:
- Sofa feels unstable: Ensure all connecting brackets are properly aligned and tightened. Check that all legs are securely screwed into the base.
- Cushions appear flat: Fluff and rotate cushions regularly. High-density foam may require some time to fully expand after unpacking.
- Covers do not fit correctly: Ensure the covers are correctly aligned with the cushions and secured with the Velcro. If covers were recently washed, ensure they are completely dry before reattaching.
