Office Chair - Swivel

The type of office chair that can rotate is commonly known as a swivel chair, which falls under the category of office chairs or computer chairs, with the English name being swivel chair.

I. Functional Features of Swivel Office Chairs
The core function of a swivel office chair is 360-degree movement, achieved through a rotating shaft mechanism that ensures smooth and uninterrupted rotation. This design allows users to easily reach various corners of their work area without frequently getting up and moving the chair, such as turning from one side of the desk to a file cabinet or printer, significantly enhancing work efficiency. Simultaneously, the swivel function reduces the number of times users need to stand up, minimizing physical fatigue and making the office experience more comfortable and enjoyable.

II. Classification and Structure of Swivel Chairs
Swivel chairs are classified into two types based on their rotation angle:

1. Semi-swivel chairs: These chairs have a rotation range of 90 degrees to the left and right, suitable for scenarios with limited space or where only minor adjustments are needed.
2. Full-swivel chairs: These chairs support unlimited 360-degree rotation and are a common choice in offices, meeting the needs for multi-directional operations.

Their structure typically includes the following core components:

• Headrest, backrest, and seat: These form the main body of human support, with some models incorporating ergonomic designs to fit the curvature of the spine.
• Armrests: These provide arm support, with some high-end models (such as the Henglin L700 series) featuring a dual-axis 5D design that supports 360-degree rotation, 7 cm of vertical adjustment, and 4 cm of horizontal movement.
• Gas lift support: This generates elastic force through the difference in piston cross-sectional area and internal high-pressure nitrogen, enabling seat height adjustment and locking at any desired height.
• Rotating shaft and wheeled five-star base: The rotating shaft connects the seat to the base, enabling rotation, while the five-star base with casters ensures flexible and stable movement.

III. Special Types and Extended Functions
Some ergonomic chairs further optimize the rotation function on the basis of traditional swivel chairs. For example, the armrests of the Henglin L700 series office gaming ergonomic chair not only support 360-degree rotation but also offer multi-dimensional adjustability to accommodate different sitting postures. Additionally, the height adjustment and locking function of the gas lift allow the seat height to be adjusted according to the user's body type or desk height, further enhancing comfort and practicality.
