The middle and high-end materials of sofa feet are zinc alloy and stainless steel, followed by wooden feet. Generally, the pipe wall thickness is 2mm, and the four sofa legs bear 200KG, which is used for the design of the lifting base. The maximum height is 15mm. It is recommended not to adjust the height more than 10mm, otherwise the bearing will be affected. The installation of sofa feet is very simple. First, install 4 screws, fix the cover on the cabinet, then screw on the tube, and adjust the height with the feet.
