Functions of Different Parts of an Office Chair
The functions of different parts of an office chair are as follows:
Casters are the mobile components of an office chair. There are two types: regular casters and PU casters. PU casters are more suitable for use on wooden floors and in computer rooms, as they can reduce damage to the floor.
The chair base is the frame that supports the chair. The thickness of the iron frame affects its service life. Surface treatment methods include painting, baking paint, and electroplating, among which electroplating offers good quality and is less prone to rust.
The gas lift is a key component for adjusting the chair's height and enabling rotation. For example, the right lever on an executive chair can control the height adjustment. Simply lift the chair slightly while sitting to raise it, and press down to lower it. When adjusting the height, keep your buttocks on the seat and use your body weight to assist in the adjustment. The most comfortable position is when your knees are bent at a 90-degree angle and your feet can rest flat on the ground.
The chair base plate mainly serves to support the seat and connect it to the gas lift, providing stable support for the seat.
The seat is composed of wood, sponge, and fabric. The quality of the wood is not easily noticeable. There are two types of sponge: recycled sponge and new sponge. Fabrics include linen, mesh, and leather. Mid-to-high-end computer chairs support slight forward and backward adjustment of the seat to accommodate people with different leg lengths, ensuring even distribution of pressure on the buttocks and legs.
Armrests provide support for the arms. Adjustable armrests can adapt to various postures such as typing, writing, and resting, effectively supporting the arms, dispersing shoulder pressure, and preventing poor postures like shoulder and neck pain.
The connection between the seat and the backrest is achieved through corner brackets that connect the seat and the backrest using steel pipes or steel plates, ensuring a stable connection.
The backrest frame is usually a combination of a plastic frame and mesh fabric, offering good breathability.
Lumbar pillows and headrests enhance comfort. A dedicated adjustable lumbar pillow can be adjusted up and down and forward and backward to precisely fit the natural curve of the lumbar spine. High-back computer chairs equipped with adjustable headrests can accommodate users of different heights, relieving neck stiffness and soreness.
The tray enables reclining and height adjustment functions. The left lever on an executive chair controls the intensity of the backrest recline, and the conventional backrest angle can be adjusted within the range of 90ยฐ to 135ยฐ.
The sliding casters facilitate quick movement and seat adjustment. The chair can rotate 360ยฐ freely, and it is equipped with silent universal wheels at the bottom, allowing smooth pushing and pulling without damaging the floor.
In terms of breathable material design, mainstream options include high-elastic mesh fabric and breathable sponge, which offer good ventilation and prevent sweating and heat buildup during prolonged sitting.
