A divan(Turkish divan, originally from Persian devan) is a piece of couch-like sitting furniture or, in the UK, a box-spring based bed. Primarily, in the Middle East (especially the Ottoman Empire), a divan was a long seat formed of a mattress laid against the side of the room, upon the floor or upon a raised structure or frame, with cushions to lean against. Divans received this name because they were generally found along the walls in Middle Eastern council chambers of a bureau called divan or diwan (from Persian, meaning a government council or office, from the bundles of papers they processed, and next their council chambers). Divans are a common feature of the divan, a long, vaulted, narrow room in Levantine homes. The sofa/couch sense was taken into English in 1702 (early 18th century).
