What is the composition of the office chair?

Composition of office chair

1. Casters Ordinary castors, PU wheels (soft materials, suitable for wooden floors and machine rooms).

2. The thickness of the chair leg iron frame directly affects the service life of the chair. Surface treatment: spray painting, baking paint (shiny surface, not easy to paint off), electroplating (wooden frame can not be electroplating), electroplating quality is good, it is not easy to rust.

3. The air rod is also called the extension rod, which is used to adjust the height and rotation of the chair.

4. The chassis supports the part of the seat, and the lower part is connected with the air rod.

5. The chair seat is composed of wood, sponge and fabric. The quality of boards is usually not felt by consumers. Sponge: regenerated cotton, new cotton. 99% of manufacturers use the two together. The thicker the harder, the higher the cost. The thickness and hardness are appropriate. Press the seat with your hand. Fabric: linen, mesh, leather. The plastic frame is pressed onto the mesh. This kind of chair is more breathable.

6. Handrails.

7. Seat back connection (corner code) The seat and seat back are separated and connected by steel pipe or steel plate, usually 6mm or 8mm thick. However, the steel plate with width less than 6cm must be 8mm thick.

8. The chair with steel frame and plastic frame on the back is made of mesh, which is breathable.

9. The waist pillow reflects the comfort of the chair.

10. The headrest represents the comfort of the chair.

The office chair is composed of seven parts: chair seat, air pole, chair back, tray, casters, five-star claw and armrest.

The office chair is generally fixed or sliding because of different use locations and methods. There are two ways to connect the chair wheel or fixed seat with the chair leg: threaded type and spring coil embedded fixed type. The sliding chair wheel uses different materials to match the sliding speed of the chair due to the different hardness of the floor. Soft wheels (PU) are used for hard floors, and hard wheels (NYLON) are used for soft floors.

The basic function of a chair is to support its body when the user is working or resting. The office chair is required to be used in both working and resting conditions. Therefore, the office chair has tilting and lifting functions to meet this requirement. The lifting of the office chair is realized by the air bar, and the tilting function is realized by the tilting mechanism of the tray.

In different working environments, the adjustment of the back angle of the office chair can help users improve their back posture to reduce back pressure. The office chair can adjust the forward tilt angle to match the user's physical activities to provide a correct sitting posture, which can reduce the pressure on the user's legs.

The seat can also be locked forward. Assuming that the user needs to use the computer for a long time, locking the seat forward can help the lower back have a greater angle to move, and reduce the pressure on the spine. The sliding of the chair wheel can help the user move quickly within an appropriate range, facilitating the drag of the chair and the adjustment of the seat.
