Basic composition of office chairs

1. Casters: ordinary casters, PU wheels (soft material, suitable for wooden floors and machine rooms).
2. Chair legs: The thickness of the iron frame directly affects the service life of the chair. Surface treatment: polishing, spray painting, baking varnish (surface gloss, not easy to peel off paint), electroplating (wooden frame cannot be electroplated), good electroplating quality will not rust easily.
3. Air rod: Also called telescopic rod, it is used to adjust the height and rotation of the chair.
4. Chassis: The part that holds up the seat, and the lower part is connected to the air rod.
5. Seat: composed of wood board, sponge and fabric. The quality of wooden boards is usually not felt by consumers. Sponge: regenerated sponge, new sponge. 99% of manufacturers use a combination of the two. The thicker and harder, the higher the cost. Appropriate thickness and appropriate hardness are enough. Press the seat with your hands. Fabric: Mayon, mesh, leather. The plastic frame presses the mesh. This type of chair is more breathable.
6. Handrail: Thickness affects quality.
7. Seat back and seat connection (corner code): The seat and back are separate and connected by steel pipe or steel plate. The steel plate is usually 6mm or 8mm thick. However, steel plates with a width less than 6cm must be 8mm thick.
8. Chair back: Steel frame and plastic frame chairs are made of a combination of mesh and are breathable.
9. Lumbar pillow: reflects the comfort of the chair.
10. Headrest: expresses the comfort of the chair.
