Compared to traditional wooden sofa legs, plastic sofa legs are more portable and more affordable, a new environmentally friendly concept. A sofa is a multi-seat, upholstered piece of furniture with armrests on both sides. Before being introduced to Asia as the focal point of Western interior design, it was originally made popular in Western countries. 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 only guard against moisture from the floor harming the sofa's bottom. Existing couch feet typically consist of a base plate and a foot cushion, and they are fixed together by welding, which is not only challenging to do. Additionally, if a sofa foot is broken in any way, the entire sofa foot needs to be taken off and replaced, The sofa tilts because a portion of the sofa foot is connected to the sofa through the thread. Because of this, the height of the sofa foot is inconsistent and increases the manufacturing cost. 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.
