The origin of the sofa dates back to ancient Egypt around 2000 BC, but the true soft sofas appeared in the late sixteenth to early seventeenth centuries. At that time, the sofa mainly used natural elastic materials such as horsehair, bird feathers and plant fluff as fillers, and the outside was covered with fabrics such as velvet and embroidery to form a soft human contact surface. For example, the Farthingle chair popularly used in the public in Europe was one of the earliest sofa chairs.
In 1828, springs began to be used in sofas. In 1904, Morris invented the assembly of springs, which were assembled into a frame of horn-shaped springs, which is the originator of modern deep-seat spring sofas. In the 1920s, Dunlop invented a new padded process, the rubber foaming process, which filled the natural rubber emulsion with a gas and then poured it into a mold to form and dry it. An elastic filler - foamed rubber. The application of foamed rubber greatly simplifies the filling process of the sofa, and has the appearance quality and functional effect of the spring cushion. In the 1960s, the success of people in the development of inflatable and water cushions marked the maturity of sofa manufacturing technology.
