Office Chair Making Tutorial

Office chair making tutorials can be divided into ordinary office chair making, swivel office chair making, factory assembly line office chair assembly, and 3D modeling office chair model creation based on different types and production methods, as detailed below:

Ordinary Office Chair Making:
Begin by constructing the base cushion frame. Place square steel tubes into a hydraulic press to bend them into a square frame with rounded corners at each corner, and weld the support steel plate to the frame opening. Next, build the internal structure by hooking S-shaped springs onto the frame and connecting three support steel bars. Then, weld and polish the armrest connectors and backrest components. After that, cut the leather by placing a plastic template on it to cut out the required shape. When making the seat cushion, adhere the leather to a harder foam cushion and trim it; for the backrest, use a softer, fluffy foam pad, cut and mark it, and then sew the leather to form pleats. Finally, assemble the entire chair by wrapping the metal frame with foam padding, covering it with the outer skin, securing the cover plate, assembling components such as the adjustable armrests and hydraulic rod, and installing the wheels, headrest, and armrests.

Swivel Office Chair Making:
Start by welding a sturdy base and installing steel springs and support frames. After completing the seat frame, weld the backrest frame. Process the leather and foam by flattening the leather and cutting it according to the template, cutting foam blocks of different densities, and sewing the leather and foam together. When assembling the seat, add particleboard and foam to the frame, wrap it with leather, install plastic cover plates, attach components such as the base and support rods, install a hydraulic rod that allows for height adjustment and 360-degree rotation, and finally attach an aluminum base, casters, headrest, and armrests.

Factory Assembly Line Office Chair Assembly:
During the component preparation stage, workers sort out more than 200 types of components and deliver them to the assembly team. For bottom assembly, place the base upside down on a fixture, attach the casters and secure them with a pneumatic press, install the pneumatic cylinder for height adjustment, fix the cylinder and tilt mechanism with a machine, bolt the crossbar in place and install the cables and control rods. For upper assembly, first secure the B-link and then fix the seat cushion onto the crossbar, install three-dimensional armrests and attach control rods to adjust height and angle, and finally attach the Y-shaped lumbar support to the backrest.

3D Modeling Office Chair Model Creation (Using 3ds Max as an Example):
First, adjust the window layout to ensure the model is symmetrical front to back. When making the tubes, convert a cube into a shell surface, select half to create a new shape, and delete the excess parts to make tubes that meet the requirements. For the seat cushion, place a cube to determine the overall shape and then refine it. When making the backrest, create a side-curved shape, adjust the number of segment lines, remove the excess parts, adjust the height, use a black line as the axis of symmetry to determine the position, and draw the outline with spline curves.
