The construction of furniture falls into different categories depending on its form and use. The throne, an impressive chair with or without a back, often without arms, is used by gods, kings and heroes. The clismos, a purely Greek creation, originates from the throne with curved legs and has a curved back without arms. The difros (stool), either a solid or folding structure, is used mainly by the populace. The bed-couch is used for sleeping and eating. It is the basic piece of furniture, used for a symposium where it could seat two or three people. There were fewer types of table compared to chairs and beds. Every home had a chest as a piece of furniture used for storage.
