Office Chair Accessories

Office chair accessories come in a wide variety, covering multiple functional modules such as support, adjustment, mobility, and connection. The main types include the following:

1. Support and Base Accessories

   • Swivel chair base components and square swivel plate chassis are the core support structures of office chairs. The former is usually circular or star-shaped, designed to disperse pressure and connect to the gas lift; the latter is mostly used for fixed seats, providing stable support.
   • High-leg swivel chair bases are suitable for scenarios where the seat needs to be raised, such as bar stools or high-table sets; thickened chair foot chassis enhance load-bearing capacity by thickening the material, extending service life.
   • Electroplated five-star foot frames are a common base type. Their five-claw design evenly distributes weight, and the electroplating process improves rust resistance, making them suitable for long-term use.

2. Height Adjustment and Regulation Accessories

   • Explosion-proof four-stage gas lifts are the core components for height adjustment, regulating seat height through air pressure. The four-stage design means higher safety and stability, capable of withstanding greater pressure.
   • Height adjustment rods and gear rod manual/electric drive screw lift mechanisms achieve seat height adjustment through mechanical or electric means, respectively. The latter is more common in high-end office chairs, supporting precise control.
   • Chair footrest adjustment cylinders allow users to adjust the height of the footrest according to their needs, enhancing comfort during prolonged sitting, commonly found in nap chairs or multifunctional office chairs.

3. Mobility and Protection Accessories

   • Alloy universal wheels are crucial for the mobility of office chairs. Their quiet and wear-resistant characteristics reduce damage to the floor while supporting 360-degree rotation, improving usage flexibility.
   • Chair foot pads are usually pasted on the bottom of the chair feet for anti-slip or floor protection. They are mostly made of rubber or silicone, suitable for hard floor environments.

4. Connection and Fixing Accessories

   • Backrest angle brackets and seat angle brackets are metal components that connect the backrest and seat cushion, ensuring structural stability through screw fixation and preventing looseness or abnormal noises.
   • U-shaped plastic tube sleeves are mostly used to wrap the metal tubes of the chair feet, preventing scratches to users or furniture while enhancing overall aesthetics.

5. Comfort Accessories

   • Office chair backrest headrest brackets are used to install headrests, supporting up-and-down or angle adjustment to relieve neck pressure, suitable for people who work at desks for long periods.

These accessories are combined through modular design, enabling office chairs to have functions such as height adjustment, mobility, support, and comfort optimization. Users can choose appropriate accessories for repair or upgrade according to their needs.
