As an alternative to traditional wooden sofa legs, plastic couch legs are more affordable and portable. They also promote environmental sustainability. A sofa is a multi-seat, upholstered piece of furniture 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 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 are solely there to keep moisture from the floor from harming the sofa's bottom. A base plate and a foot cushion normally make up the couch feet that are now in use,and they are fixed together by welding, which is not only challenging to do.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 couch feet may rectify this tilt, significantly boost their durability, and lower the cost of producing sofas, opening up a whole new universe for sofa feet.
