The basic composition of office chairs

1: Castors: ordinary casters, PU wheels (soft materials, suitable for wooden floors and computer rooms).

2: Chair legs: The thickness of the iron frame directly affects the service life of the chair. Surface treatment: polishing, spray painting, baking paint (surface gloss, not easy to peel off paint), electroplating to remove picture books (wooden frames cannot be electroplated), good electroplating quality is necessary to prevent rusting.

3: Air rod: also known as extension and lowering rod, used to adjust the height and rotation of a chair.

4: Chassis: The part that supports the seat and is connected to the air bar below.

5: Chair seat: composed of wooden boards, sponge, and fabric. The quality of wooden boards is usually not perceived by consumers. Sponge: regenerated cotton, new cotton. 99% of manufacturers use a combination of the two. The thicker and harder the material, the higher the cost. The appropriate thickness and hardness are sufficient. Hand press the chair seat, fabric: linen, mesh, leather. Press the plastic frame onto the mesh. This type of chair is more breathable.

6: Armrests: Thickness affects quality.

7: Seat back connection (corner code): The seat and back are separated and connected using steel pipes or steel plates, which are usually 6mm or 8mm thick. But steel plates with a width less than 6cm must be 8mm thick.

8: Chair back: A chair with a steel frame and a plastic frame, made of a combination of mesh and breathability.

9: Waist pillow: reflects the comfort of the chair.

10: Headrest: Indicates the comfort of the chair.
