What are the composition structures of office chairs?

Generally speaking, office swivel chairs can be divided into three series: large class chairs, middle class chairs and staff chairs. The structural composition of each series of office swivel chairs is different. The structure of the large class chair mainly includes high backrest, casters, cushions, five-star legs, functional chassis, air poles and handrails. The structure of the middle shift chair mainly includes a low backrest, casters, cushions, five-star legs, a functional chassis and a drying rod. The staff chair structure mainly includes a low backrest, casters, cushions, five-star legs, a functional chassis and a drying rod.

1, backrest. Backrest is generally composed of steel frame or plastic frame and breathable mesh cloth.

2. Casters. Casters can be divided into ordinary casters and PU casters, among which PU casters are more suitable for wood floors.

3. Cushion. Wood, fabric and sponge make up a soft cushion. The fabrics are usually green leather, Italian leather, Thai leather, chemical fiber hemp and so on. Among them, green leather is the first-class raw material for making senior class chairs, followed by Italian leather and Thai leather, and most staff chairs use chemical fiber linen fabric.

4, five-star feet. Office swivel chairs mostly use five-star feet, and the materials are mainly iron-chromium electroplating and aluminum alloy. Fe-Cr electroplating structure is relatively stable, but the bottom is easy to rust, while aluminum alloy structure is firm. If it is only polished for a long time, the surface will become dark.

5. Functional chassis. The chassis is a component supporting the base, and the lower part is connected with the air rod.

6. Air pole.

Air lever, also called lifting lever, can be used to adjust the height and rotation of swivel chair.
