A "sectional" refers to a type of sofa or couch that is made up of multiple sections or pieces. These pieces can be arranged in various configurations, allowing for flexibility in design and seating arrangements. Sectionals are popular in living rooms because they can accommodate more people than traditional sofas and can fit into different spaces. Sectionals often come in various styles, materials, and colors, making them suitable for different interior designs. They can include features like reclining seats or built-in storage. Many people choose sectionals for their comfort and versatility, making them a practical choice for family gatherings or entertaining guests.
