Swivel Office Chair

A swivel office chair is a type of chair with a seat that can rotate 360 degrees. It belongs to the category of office chairs or computer chairs, with the English name 'swivel chair'. It features flexible mobility and diverse functions.

Core Functions and Structure
The core function of a swivel office chair relies on a gas lift for height adjustment. It generates elastic force through the difference in cross-sectional areas between the high-pressure nitrogen inside and the piston, supporting the user's weight and allowing height adjustment that can be locked at any position. Its structure typically includes a headrest, backrest, seat, armrests, gas lift support, swivel mechanism, and a five-star base with wheels. Based on the rotation angle, it can be classified into semi-swivel chairs (90 degrees left and right) and full-swivel chairs (360-degree rotation). Common types include task chairs, staff chairs, mid-back chairs, and executive chairs, suitable for various office settings.

Adjustable Features of High-End Models
Some high-end models, such as the Woshi Tiance ULTRA and Tiance AIR20, offer richer adjustable functions:

• Headrest: Equipped with 4D adjustment capabilities, supporting 5 cm of vertical movement, 6 cm of horizontal extension, angle rotation, and dual-joint adjustment, precisely adapting to the cervical support needs of users of different heights.
• Armrests: Upgraded to 8D adjustment specifications, supporting synchronized recline with 360-degree rotation and upward tilt. Using aluminum alloy brackets and connecting shafts, they allow vertical, horizontal, inward, and outward movement, with the armrest surface rotating 360 degrees and tilting forward and backward, providing a crisp and smooth feel.
• Lumbar Support: The lumbar support area is large and can be adjusted up and down with the backrest, allowing it to be positioned where the user desires. It also offers multi-level adjustable lumbar tracking, with adjustable lumbar support distance.
• Backrest: Supports up to 5 levels of vertical adjustment, with a wide adjustment range, suitable for users of different heights.
• Seat Depth: Supports 5 cm of forward and backward adjustment to accommodate different body types.
• Recline: Supports a maximum of 145-degree angle adjustment, with multiple locking positions. The resistance of the adjustment knob can be customized according to preference or body weight.

Purchase Considerations
When purchasing, consider style, color, and spatial compatibility. Factors such as the shape of the base, back height design, and armrest material affect the style. Color selection should be based on the usage scenario; for example, a high-back model is suitable for a study, while a streamlined design is ideal for a workshop. Quality assessment should focus on seat comfort testing, wheel stability, and gas lift reliability. Prices range from tens to tens of thousands of yuan, so a comprehensive choice should be made based on functionality and quality.
