Based on the provided context and general knowledge, a sectional sofa is a type of upholstered seating furniture that comprises multiple independent pieces or sections. These sections can be arranged in various configurations to create a single, larger seating unit tailored to a specific space. The snippets from Bassett Furniture and Castlery confirm that sectionals are a distinct category of sofa, but they do not provide a detailed definition.
Unlike a traditional, single-piece sofa, a sectional's multi-piece allows for greater versatility in room layout and seating capacity. The most common configurations are the L-shape, which is ideal for corners, and the U-shape, which offers extensive seating and can help define a conversational area within a larger room. The individual components that make up a sectional can include elements like an armless loveseat, a corner piece, a chaise lounge, or a recliner, which are joined together to form a cohesive whole.
