Compared to traditional wooden sofa legs, plastic sofa legs are more portable and more affordable, a new environmentally friendly concept. A multi-seat, upholstered piece of software furniture with armrests on both sides is known as a couch. It was first popularized in Western nations before being brought to Asia as a centerpiece of Western interior design.The frame of the chair is made of wood or steel and lined with cotton and other foam materials, which makes it more comfortable overall. The feet at the bottom of the sofa support the seat and serve only to prevent damage to the bottom of the sofa from dampness from the floor. The base plate and foot cushion of most commonly used sofa feet are joined together by welding, which is not only difficult to execute. And when part of the sofa foot is damaged, the whole sofa foot must be removed and replaced, the manufacturing cost is high, part of the sofa foot is connected to the sofa through the thread Some sofa feet are connected to the sofa seat through the thread, this will cause the height of the sofa foot is not consistent, resulting in sofa tilt. The plastic sofa feet can balance this tilt and greatly increase the solidity of the sofa feet and also reduce the cost of sofa production, making it a new world for sofa feet.
