Based on the provided context, a chaise on a sofa refers to a specific section of the couch that is elongated, allowing a person to put their feet up and recline. This feature creates what is known as a "chaise sofa" or a "chaise sectional."
Essentially, the chaise portion acts like a built-in ottoman or footrest, extending forward from one end of the main sofa seating. This design provides a dedicated space for lounging comfortably without needing a separate piece of furniture.
The search result titles help distinguish this from other furniture types. A "chaise sofa" is different from a "chaise lounge," which is a standalone piece of furniture. It is also distinct from a "corner sofa," which typically has full backrests along both sides of its L-shape, whereas the chaise section of a sofa often has a low-profile arm or no arm on one side, functioning primarily as a leg rest.
