Functions of Office Chair Accessories

The accessories of office chairs and their functions are as follows:

Basic Support and Mobility Accessories
Casters are the core components for the mobility of office chairs, divided into ordinary casters and PU wheels. The latter, due to the characteristics of soft materials, are more suitable for wooden floors and computer rooms, preventing scratches on the ground. The chair legs, as the supporting frame, have an iron frame thickness that directly affects the service life. Surface treatment methods include polishing, painting, baking paint, and electroplating, among which electroplating significantly enhances rust resistance. The gas lift (height-adjustable rod) achieves height adjustment and rotation functions of the chair through pneumatic regulation, meeting the needs of different heights and sitting postures. The base connects the gas lift to the seat and supports the backrest simultaneously. Its design determines the smoothness of the chair's recline and the convenience of adjustment.

Core Accessories for Seating Comfort and Support
The seat is composed of a wooden board, sponge, and fabric. The quality of the wooden board, although hidden, affects stability. The thickness and density of the sponge determine comfort, while the fabric offers various options such as linen, mesh, and leather to adapt to different usage scenarios. The backrest usually combines a steel or plastic frame with mesh fabric, balancing support and breathability. The lumbar pillow conforms to the physiological curvature of the waist, dispersing the pressure from prolonged sitting. A high-quality lumbar pillow should have continuous support. The headrest (neck pillow) provides additional support for the neck, relieving shoulder and neck stiffness. Memory foam material enhances the sense of enclosure. Among seat cushions, back cushions, and lumbar supports, memory foam conforms to body curves with its slow rebound characteristics, latex excels with its natural elasticity, and gel improves comfort by enhancing breathability.

Functional Expansion Accessories
Armrests reduce arm fatigue by providing elbow support. Thicker armrests are more durable, and some products have height adjustment functions to match the desktop. Footrests or stools improve sitting posture by supporting the feet, preventing the habit of crossing legs and promoting leg blood circulation. Office chair pouches or storage bags utilize vertical space to store small items, and the compartmentalized design improves organization efficiency. Chair covers combine dust and stain prevention with style transformation functions. Cotton and linen materials are breathable and skin-friendly, leather materials are durable and easy to clean, and elastic fabric is versatile. Wheel stoppers or foot covers protect the floor and reduce noise by restricting movement or adding cushioning.

Structural Connection Accessories
The backrest-seat connection (corner brace) uses steel pipes or plates to fix split backrests. The thickness of the steel plate needs to be adjusted according to the width to ensure structural stability. These accessories together form the functional system of office chairs, comprehensively covering user needs from basic support to ergonomic optimization, as well as space utilization and maintenance convenience.
