"sofa" is a foreign word, transliterated from the English word sofa. This is a multi-seat chair with cushions. An armchair with springs or thick foam plastic and armrests on both sides is a kind of soft furniture. The origin of sofa can be traced back to ancient Egypt around 2000 BC, but the real soft bag sofa appeared from the end of16th century to the beginning of17th century.
