All Accessories for Office Chairs

The full range of accessories for office chairs varies depending on the model and brand. Common accessories can be divided into two categories: basic structural components and functional adjustment components. Below are descriptions of typical accessories:

I. Basic Structural Components

1. Five-Star Base: As the core component supporting the chair body, it is usually made of nylon or metal. It disperses pressure through five legs to ensure stability. Some high-end models are equipped with electroplated five-star bases to enhance load-bearing capacity.
2. Casters: Installed at the bottom of the five-star base, enabling 360-degree rotation and movement. They are mostly made of hard plastic or rubber. It is important to pay attention to the load-bearing parameters to avoid deformation after long-term use.
3. Gas Lift/Height Adjustment Rod: A key component connecting the five-star base to the seat cushion, it adjusts the seat height through pneumatic or mechanical structures. It is essential to choose explosion-proof Class 4 gas lifts for safety, as poor-quality gas lifts may pose an explosion risk.
4. Seat Cushion: The part that directly bears the weight of the human body. Common materials include foam, mesh fabric, or memory foam. Some models come with removable seat cushions for easy cleaning or replacement.
5. Seat Plate: A metal structural component located beneath the seat cushion, connecting the gas lift to the cushion. It usually includes a tilt adjustment function, allowing the user to maintain balance when leaning back.

II. Functional Adjustment Components

1. Armrest System:
   • Fixed Armrests: Directly connected to the seat cushion or seat plate, with no adjustable height or angle.
   • 8D Adjustable Armrests: Support multi-dimensional adjustments such as up and down, front and back, and left and right rotation, adapting to different usage scenarios.
   • Armrest Brackets: Independent metal brackets from the seat cushion that can be replaced or upgraded separately.
2. Backrest Components:
   • Backrest Cover: A decorative piece covering the backrest frame, which may include breathable mesh fabric or leather material.
   • Back Angle Adjuster: A mechanical structure for adjusting the tilt angle of the backrest, commonly found in office chairs that can recline.
3. Headrest System:
   • Headrest Bracket: A metal piece connecting the headrest to the backrest, supporting height or angle adjustments.
   • Detachable Headrest: Some models offer an independent headrest fixed by a bracket.

III. Auxiliary Accessories

1. Screws and Tools: Includes long screws (for connecting armrests to the seat cushion), short screws (for fixing the seat cushion to the seat plate), and matching screwdrivers for assembly or repair.
2. Chair Feet Pads: Pasted at the bottom of the five-star base to prevent scratching the floor or increase friction.
3. Tube Sleeves and Clamps: Metal sleeves used to secure the gas lift or height adjustment rod, preventing loosening.

Notes: Accessories may vary among different brands and models. For example, gaming chairs may include lumbar supports or 4D armrests, while minimalist models may omit headrests. It is recommended to obtain a complete list through the product manual or by consulting the merchant to avoid compatibility issues caused by self-assembly.
