Office Chair Bottom Image

Admin October 12, 2026

I cannot directly provide an image of the bottom of an office chair, but I can describe its common styles and components in detail.

Common Styles

  • Five-Star Base: This is one of the most common styles for the bottom of an office chair, typically made of metal (such as steel or aluminum alloy) or nylon. It features a radial five-claw design with casters at the bottom, providing strong load-bearing capacity and flexible movement. This design is commonly found in ergonomic chairs and gaming chairs, which require high comfort and mobility.
  • Bow Base: Made by bending a metal frame into a bow shape, it rests directly on the ground without wheels. This base is structurally stable, providing reliable support for the office chair, and is suitable for conference chairs and staff chairs, offering a simple and durable design.
  • Fixed Wood Base: Made of solid wood, it comes in various shapes, such as round or square. This base is often used in vintage-style or high-end office chairs. Although it lacks mobility, it offers excellent stability and adds a touch of elegance and solemnity to the office chair.
  • Swivel Base: Equipped with a height adjustment function, it connects the seat and the frame at the bottom, supporting 360-degree rotation. This design is commonly found in executive chairs and adjustable office chairs, facilitating flexible direction adjustment during work.

Components

  • Chair Legs: A crucial part that supports the overall structure of the office chair, commonly made of metal, nylon, or solid wood. The bottom is often designed as a five-star base, which evenly distributes pressure and enhances the stability of the office chair.
  • Casters: Installed at the end of the chair legs, they come in two types: regular casters and PU wheels. Casters can rotate 360 degrees, allowing the office chair to move easily in all directions and meet the flexible needs of users in the office space.
  • Gas Cylinder (Height Adjustment Rod): Located at the center of the chair legs, it connects the base to the seat. By adjusting the gas cylinder, the height of the seat can be easily adjusted, and it also supports the rotation function of the seat, making the office chair more ergonomic.
  • Base Plate: Connects the gas cylinder to the seat and controls functions such as the recline angle. However, the base plate is usually hidden by the seat and is not directly visible from the bottom appearance.
