The volume of the seat cushion, armrests, backrest, and backrest ears is compressed by vacuuming. The extension components are packed into a carton in sheet form. The support rod, drive rod, and push rod motor are also packed into the carton as parts, thereby increasing the packing volume and reducing transportation costs. After receiving the goods, the customer opens the package and restores the seat cushion, armrests, backrest, and backrest ears to their original positions. Using the provided tools, the extension assembly is first installed on the inside of the armrest. This is done by tightening the provided bolts to install the front and rear mounting plates onto the armrest frame. Then, the support rod is installed onto the third bracket using bolts, and the drive rod is installed onto the leg link three using bolts (the drive rod and connector do not need to be separated). The push rod motor is installed between the support rod and the drive rod (hinged together by bolt assembly). The seat cushion is then installed onto the first and second brackets. The backrest is inserted into the backrest mounting plate using snap fasteners, and the backrest ears are inserted into both sides of the backrest using male and female snap fasteners. The operation is very convenient.
