Shot glass-shaped cabinet legs are made of solid iron. This kind of iron material has been specially treated to have sufficient strength and hardness to bear the weight of the sofa and the user. On the top of the cabinet legs, there is usually a connecting device. This connecting part is designed to fit closely with the sofa frame to achieve a stable connection. Common connection methods include screw fixing, rivet connection or welding. Its precise size and firm connection ensure the stability between the cabinet legs and the main body of the cabinet, preventing them from loosening or falling off during use.
