4. Operating Instructions

Your Korser U-Shaped Sectional Sofa is designed for versatile use and comfort.

  • Modular Configuration: The sofa's modular design allows for flexible arrangement. While typically configured as a U-shape with dual chaises, the sections can be adjusted to suit your living space needs.
  • Comfort Features: The sofa features thickened, high-density foam and resilient springs for supportive seating. The extra-wide padded armrests can also serve as comfortable headrests for temporary lounging.
  • Clearance: The sofa provides 7 inches of clearance from the floor, allowing most robot vacuums to pass underneath for easy cleaning.

5. Maintenance and Care

Proper care will extend the life and appearance of your Korser sofa.

  • Removable Covers: Both the plush backrests and seat cushions feature fully detachable, zippered covers.
  • Washing Instructions: The chenille fabric covers are machine washable. Remove the covers and follow the care instructions on the label, typically using a gentle cycle with cold water and mild detergent. Air dry or tumble dry on low heat to prevent shrinking or damage.
  • 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.
  • Regular Cleaning: Vacuum the sofa regularly using an upholstery attachment to remove dust and debris.
  • Frame Care: The robust solid wood frame requires no special maintenance. Avoid exposing it to excessive moisture or extreme temperature changes.

  • Loose Cushions: Re-fluff and adjust cushions regularly to maintain their shape and position.
  • Difficulty Connecting Sections: Ensure the connectors are correctly aligned. Apply firm, even pressure to engage the locking mechanism.
