Office Chair Accessories

Office chair accessories come in a wide variety, covering multiple functional modules such as bases, height adjustment mechanisms, supports, and connections. Different types of accessories vary in materials, specifications, and uses. The following provides an explanation from two dimensions: general accessories and specific model accessories.

General Office Chair Accessories

1. Base and Support Structures

   • Swivel Chair Bases: These include square swivel bases, leisure chair swivel bases, etc. They are typically made of metal or engineering plastics and use rotating mechanisms to adjust the seat direction. For example, electroplated five-star bases and steel five-claw bases disperse pressure through the five-claw structure, enhancing stability.
   • Foot Pads and Anti-Tip Devices: Chair foot pads (such as anti-tip arch foot pads) reduce sliding risks by increasing the contact area; high-leg swivel chair bases are designed for specific height requirements, suitable for different usage scenarios.

2. Height Adjustment and Control Components

   • Hydraulic Gas Springs: The hydraulic gas spring cylinder in computer chairs is the core component for height adjustment, using pneumatic or hydraulic principles to adjust seat height. It must comply with safety standards to avoid bursting risks.
   • Height Adjustment Cylinders and Drive Screws: The footrest height adjustment cylinder in chairs is used to adjust the footrest height; manual or electric drive screws are applied in height-adjustable desk accessories, achieving precise height control through thread rotation.

3. Functional Attachments

   • Casters and Brake Devices: Alloy universal casters and plastic threaded brake casters enhance mobility through 360-degree rotation or braking functions. Hard or soft wheels should be selected based on the floor type.
   • Headrests and Supports: The headrest support for office chair backs (such as the adjustable height PA simple headrest) allows for up-down or angle adjustments through buckle or slide rail structures, relieving neck pressure.

4. Connection and Fixing Components

   • Corner Braces and Screws: Furniture hardware back corner braces and seat corner braces are used to fix the chair back and seat; hexagon socket screws come in two specifications: M6 (for general connections) and M8 (for load-bearing parts), which must match the reserved holes to avoid loosening.

Specific Model Accessories (Taking the opendesk slim chair as an example)
This model's accessories include connecting keys, seat surfaces, backrests, and two legs, featuring a modular design:

• Connecting Keys: As the structural core, they fix various components through mortise-and-tenon or snap-fit methods, allowing assembly without additional tools.
• Seat Surface and Backrest: These usually use multi-layer boards or composite materials, with surface treatments that balance wear resistance and comfort.
• Two Legs: Designed simply but required to bear the main weight, they are mostly made of solid wood or metal, possibly equipped with anti-slip pads at the bottom to enhance stability.

Purchase Recommendations: When selecting accessories, pay attention to material durability (such as rust-proof treatment for metal parts), specification compatibility (such as the gas spring stroke matching seat height requirements), and safety certifications (such as the gas spring passing BIFMA standard tests). For specific model accessories, strictly follow the product manual to avoid instability caused by mixing different parts.
