what is the difference between a sofa and a sectional

[MacEloise]

The provided context from furniture retailers categorizes sofas and sectionals as distinct product types, but does not include the specific text that defines the differences between them. Based on standard industry definitions, the primary distinction between a sofa and a sectional lies in their shape, construction, and configuration.

A sofa is a single, self-contained piece of upholstered furniture, typically designed in a straight line to seat two or more people. It consists of one solid frame with a back and arms. Sofas come in various sizes, such as loveseats for two people or standard three-seat versions, but they remain a singular, non-modular unit. Their linear shape makes them a versatile choice that can be placed against a wall or used to divide a space.

A sectional, by contrast, is a multi-piece sofa composed of several independent sections that can be arranged in various configurations. This modular design is its key feature. Common shapes for sectionals include the L-shape and the U-shape, which are created by connecting pieces like a chaise lounge, a corner wedge, or armless single-seat units. Because of their size and shape, sectionals are often used to anchor a large living room, fit into a corner, and provide more seating capacity than a traditional sofa.
