Compared to traditional wooden sofa legs, plastic sofa legs are more portable and more affordable, a new environmentally friendly concept. A sofa is a type of software furniture, an upholstered multi-seat with armrests on both sides. It originated in Western countries and was later introduced to Asia as one of the focal points of Western decor or modern home design. The chair's steel or wood frame, which is covered in cotton and other foam materials, makes it more comfortable overall.The sofa's feet at the bottom support the seat and merely shield the bottom from moisture on the floor, which may otherwise cause harm.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.
