What is a sofa?
Sofa (known as Couch in North America) is a kind of software furniture. It is a multi-seat chair with cushions and armrests on both sides. It originated in Western countries, and then introduced to Asia, becoming one of the focus of Western-style decoration or modern home design. The frame is a chair made of wood or steel lined with cotton wool and other foam materials, which is more comfortable overall.
The origin of the sofa can be traced back to ancient Egypt around 2000 BC, but the real upholstered sofa appeared from the end of the 16th century to the beginning of the 17th century. At that time, sofas were mainly filled with natural elastic materials such as horsehair, poultry feathers, and plant fluff, and were covered with fabrics such as velvet and embroidery to form a soft human contact surface. For example, the Farthingle chair, which was popular in Europe at that time, was one of the earliest sofa chairs. Reviewing the history of the development of sofas in China, the "Jade Table" of the Han Dynasty should be first introduced. The "Jade Table", a seat with a thick layer of fabric, depicted in "Xijing Miscellany" can be regarded as the "ancestor" of the Chinese sofa.
