Ordinary Office Chair Manufacturing

Ordinary office chair manufacturing is a systematic process that integrates R&D, material selection, precision manufacturing, and quality inspection, with the core focus on dual control over materials and craftsmanship.

Material Selection

• Wood Panels: The wood panels used for seat cushions and backrests must meet the environmentally friendly E0 standard, with extremely low formaldehyde emissions to ensure the health and safety of users.
• Metal: The metal frames are mostly made of thickened cold-rolled steel, which undergoes high-temperature rust and corrosion prevention treatments. They have strong load-bearing capacity and can last for more than ten years under normal use, providing stable support for the chairs.
• Foam: The resilience and density of the foam directly affect the sitting experience. High-density foam provides uniform support, is less likely to collapse, and remains comfortable even after prolonged use.
• Upholstery: For office chairs with leather upholstery, the leather needs to be smoothed out, and patterns are cut according to cardboard templates, avoiding natural blemishes on the leather to obtain all the leather needed for making the chair. The foam pads for the back of the chair are also cut to ensure an aesthetically pleasing and durable appearance.

Manufacturing Process

• Frame Production: Hydraulic-powered machines are used to bend steel tubes into shape to produce the frame for the bottom cushion. The ends are connected, and steel bars are welded in the middle to support the mechanism for adjusting the seat position. Then, S-shaped steel springs are hung from the front to the back of the seat frame to provide elastic support. Horizontal bars are placed and clamped onto the springs to increase stability and support.
• Back Construction: The back frame of the chair, including components such as the spine and armrest attachments, is constructed. The burrs and other rough parts on the steel are ground down to ensure safety during use.

Craftsmanship Standards

• Strict Quality Inspection: Every step of the process, from panel cutting, grinding, painting to assembly, undergoes strict quality inspection. For example, the metal welds must be smooth and firm, and the pneumatic rods of the chairs must pass safety explosion-proof tests.
• Modular Design: Many chair factories adopt a modular structure, which allows users to flexibly adjust the height and angle of components and facilitates later maintenance and replacement.

Ergonomic Design

• Curved Fit: Modern office chairs generally adopt a curved fit design, which can adapt to users of different heights and body types through adjustable lumbar supports, seat depths, and armrests.
• Pressure Dispersion: The curve of the backrest follows the natural curvature of the spine, dispersing the pressure on the upper body. The front end of the seat cushion adopts a waterfall design to reduce pressure on the back of the thighs and enhance office comfort.
