Office Chair Part Names
The main part names and functions of office chairs are as follows:
1. Casters
Casters are the mobile devices at the bottom of office chairs, typically divided into two types: regular casters and PU wheels. PU wheels are soft in material, suitable for use on smooth floors such as wooden floors or computer rooms, reducing scratches and noise; regular casters are more suitable for rough floors like carpets. The material and design of casters directly affect the chair's mobility and floor protection.
2. Chair Base
The chair base is the metal frame that supports the entire chair, and the thickness of its iron frame directly affects its service life. Surface treatment methods include polishing, painting, baking paint, and electroplating, among others, which can enhance the corrosion resistance and aesthetics of the chair base. For example, electroplating treatment can enhance rust resistance, making it suitable for use in humid environments.
3. Gas Lift (Height Adjustment Rod)
The gas lift is the core component for adjusting the chair's height and rotation, achieving stepless height adjustment through pneumatic or hydraulic principles. High-quality gas lifts need to pass safety certifications (such as BIFMA standards) to avoid explosion risks. Some high-end gas lifts also support multi-level locking functions to meet the needs of users of different heights.
4. Chair Base Plate
The chair base plate connects the seat to the gas lift, serving functions of fixation, support, and feature implementation. It fixes the seat through bolts or clips and integrates reclining mechanisms (such as synchronous tilting, locking angles) and height adjustment buttons. The material (such as steel or engineering plastics) and structural design of the base plate determine the chair's stability and durability.
5. Seat
The seat consists of three layers: wood board, sponge, and fabric. The wood board provides basic support, the sponge determines comfort (higher density means more durability), and the fabric options include linen, mesh, and leather. Mesh fabric offers good breathability, suitable for summer use; leather fabric is easy to clean but requires regular maintenance to prevent cracking.
6. Armrests
The thickness of the armrests directly affects the user experience. Thicker armrests are usually filled with high-density sponge, which does not deform easily after long-term use. Some armrests support height, angle, or forward-backward adjustments to adapt to different office scenarios (such as typing or resting).
7. Seat-Back Connection (Corner Bracket)
When the seat and backrest are designed separately, they need to be connected by corner brackets made of steel pipes or steel plates. The material and welding process of the corner brackets determine the connection strength, preventing looseness or abnormal noise after long-term use.
8. Backrest
The backrest usually adopts a steel frame or plastic frame, covered with mesh or sponge fabric. Mesh backrests offer strong breathability, suitable for long-term use; sponge backrests provide softer support. Some backrests are designed to conform to ergonomic curves, fitting the natural shape of the spine.
9. Lumbar Pillow
The lumbar pillow is a key component for enhancing comfort, providing additional support to the waist by filling with sponge or memory foam, reducing fatigue from prolonged sitting. Adjustable lumbar pillows (such as those that can move up and down or forward and backward) can adapt to the needs of users of different body types.
10. Headrest
The headrest is usually fixed at the top of the backrest, supporting height and angle adjustments to provide support to the neck. For users who work at a desk for long periods, the headrest can relieve cervical spine pressure and prevent occupational diseases.
11. Dust Cover
The dust cover covers the top of the gas lift, preventing dust from entering the internal structure and extending the service life of the gas lift. Some dust covers are designed with elasticity to fit gas lifts of different sizes.
