What is a sofa?
A sofa is defined as an upholstered bench or seat featuring arms and a back, allowing people to sit comfortably. This is the most common word used nowadays to describe the comfy piece of furniture we all relax on in the living room.
What is a couch?
The couch originated in French interior design in the 17th century, and consisted of a lounge seat with supports at both ends, but with no back support, unlike a sofa as we know it today. Instead, a couch was very similar to a traditional daybed or chaise longue. The name likely came from the french word coucher, meaning to sleep. The word couch is still widely used across the USA to describe a sofa.
What is a settee?
The settee originated in the Middle Ages, and whilst it had a design more similar to the sofa as we know it, was typically made from wood, and typically featuring an elegant and intricately carved back.
