Plastic office chair accessories refer to various structural or functional components made of plastic (such as PP, nylon, ABS, and other engineering plastics) in office chairs. They are mainly used to support, connect, adjust, or protect the main body of the chair. These accessories play a crucial role in ensuring the stability, comfort, and durability of the chair.
Five-star base/five-claw base: The plastic base frame supporting the entire chair, usually made of nylon or PP, capable of bearing weight and housing casters.
Armrests and armrest supports: Some office chairs use plastic armrests, which may have swivel or height adjustment functions.
Chair leg pads/duckbill pads/spring clips: Used to secure the casters to the five-star base, preventing loosening and reducing noise.
Chassis/swivel base: The core plastic component connecting the gas spring to the five-star base, supporting the seat cushion and backrest.
Headrest/backrest support: Some heightened headrests or neck support accessories use a plastic structure.
Cast/pulley assembly: Although containing metal axles, the outer ring is often made of plastic (such as nylon or PU) to achieve silent movement.
