[0002] The origin of sofas can be traced back to ancient Egypt around 2000 BC, but the real soft-covered sofas appeared in the late 16th and early 17th centuries. At that time, sofas were mainly filled with natural elastic materials such as horsehair, bird feathers, and plant hair, and covered with fabrics such as velvet and embroidery to form a soft surface for human contact. For example, the Farthingle chair, which was popular in Europe at that time and used by the public, was one of the earliest sofa chairs. Looking back at the history of sofa development in China, the "Jade Table" of the Han Dynasty should be the first to be recommended. The "Jade Table" with a thick layer of fabric described in "Xijing Miscellaneous Records" can be regarded as the "ancestor" of Chinese sofas.
