A "three-piece suite" commonly refers to a set of matching furniture consisting of a sofa and two armchairs. However, there are other terms used to describe this type of furniture set. One alternative is a "living room set" which often includes additional matching pieces such as a coffee table and end tables. Another synonym is "seating group" which is a broader term that encompasses any grouping of chairs or sofas designed for sitting together. Additionally, "sitting room suite," "lounge suite," and "family room set" are other terms used to describe the same type of furniture arrangement. Ultimately, the terminology used often depends on regional or personal preferences.
