Various Accessories for Office Chairs

Office chair accessories come in a wide variety, covering aspects such as support, adjustment, connection, and auxiliary functions, mainly including the following types:

1. Basic Support and Mobility Accessories

   • Wheels and Gas Springs: Wheels (such as casters) are the core components for the mobility of office chairs, commonly made of alloy or plastic, with some featuring brake functions; gas springs adjust the seat height by compressing gas and must comply with explosion-proof standards (such as Class 4 gas rods).
   • Chair Base: Including electroplated five-star bases, steel five-claw bases, etc., providing stable support, mostly made of metal with rust-resistant and wear-resistant surface treatments.
   • Chair Feet Pads: Such as bow-shaped feet pads and anti-tipping feet pads, used to balance the seat or prevent sliding, with some designs adjustable in height to accommodate different floor surfaces.

2. Structural Connection and Fixing Accessories

   • Screws and Washers: Used to fix various components, available in various specifications (such as M630, M830), with washers (6mm, 8mm) distributing pressure and preventing loosening.
   • Back and Seat Connectors: Metal connectors used to fix the chair back and seat cushion, enhancing structural stability.
   • Decorative Covers: Cover screws or connection points, improving aesthetics while preventing dust from entering.

3. Adjustment and Comfort Accessories

   • Height Adjustment Accessories: Including hydraulic gas rods, cylinders, lifting rods, etc., adjusting seat height through mechanical or pneumatic principles, with some equipped with gear rods or electric drive screw lifters for more precise adjustment.
   • Headrest and Its Bracket: The headrest connects to the chair back via a bracket (such as an adjustable-height PA simple version), providing neck support, with brackets often designed to be adjustable to accommodate different heights.
   • Armrests: Fixed or adjustable, mostly made of plastic or metal, with some supporting height and angle adjustments to enhance comfort.

4. Special Function Accessories

   • Swivel Chair Base Accessories: Such as square turntable bases and leisure chair turntable bases, supporting 360-degree rotation of the seat, with base materials needing to withstand weight and ensure smooth rotation.
   • Bar Stool Accessories: Including connected footrests, high stool integrated lifting rods, etc., designed for bar stools or high stools to meet specific usage scenario needs.
   • Feet Pad Plugs: Such as threaded hole plugs and round T-shaped anti-slip feet pads, used to seal unused holes or prevent feet pads from sliding, enhancing safety.

5. Protection and Auxiliary Accessories

   • Bow-shaped Chair U-shaped Plastic Tube Sleeves and Tube Clamps: Protect metal tubes from wear or scratches while fixing tube positions.
   • Round Tube Opening Forked Feet Covers: Cover the bottom of chair feet, reducing noise and protecting the floor.

The design of office chair accessories must balance functionality, durability, and safety, with selections made based on usage scenarios (such as office or leisure) and ergonomic needs.
