What is a single couch called?

A single couch may also be called a settee. It is a long seat made for more than one person. Settees are typically small seats that can fit two or more people, but they aren’t as wide as couches or sofas. A settee is more intimate and offers more sitting room than an armchair. Settees often have a backrest for optimal support and are frequently upholstered. On 1stDibs, shop a range of antique and vintage sofas and settees today.
