To be mobile, it must be mobile. However, since furniture presupposes a certain degree of residential permanence, it is understandable that independent types of furniture have not been developed among Melanesians or Inuit in Greenland or Mongolian nomads in Asia.
The word chair seems to have originated from the ancient Greek word kathedra, which is made up of the words kata (“down”) and hedra (“seat”). This eventually became the Latin word cathedra, meaning “seat”, and then evolved into the French chaire. The etymology of this word also gives some insight into the history of the product itself.
The root word of bed is still somewhat debated. It may have come from the Old English word bedd or the Proto-Germanic word badjan, meaning “dug sleeping place”. It could also be related to the German Bett.
During the twentieth century, however, it ceased to be used by native speakers. A single item of furniture, such as a chair or a table, is often called a piece of furniture. In many languages “piece of furniture” is one word, and often its plural form is the equivalent of the English “furniture”, for example French meuble.
