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 chair is more comfortable overall because of its steel or wood structure, which is coated with cotton and other foam components.The sofa feet at the bottom of the sofa provide support for the seat and simply prevent damage to the bottom of the sofa from moisture on the floor. Existing sofa feet generally consist of a foot cushion and a base plate, between which the fixing is achieved by welding, which is not only difficult to work with. 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.
