The simplest description of a sofa is that it is a long, upholstered seat. It usually has arms and a back, but, with all the countless designs and interpretations of the standard sofa, these are not necessary features. Another term used for sofa is couch—the differences in usage are due to regional differences in English and do not reflect different properties of the furniture. The sofa is one of the more expensive pieces of furniture that many people own.
It may be safe to say that most living rooms have a sofa. It is often part of a grouped ensemble that creates a conversation area or a place from which family members can watch television together. Often you will find a four-piece set that includes a sofa, loveseat, chair, and ottoman; or a three-piece set with sofa, loveseat, and chair. Also available are sofa, loveseat, and rocker sets.
