Swivel Chair - Office Chair Translation

A swivel chair is a type of chair with a rotatable seat, belonging to the category of office chairs or computer chairs. Its English name is swivel chair, and it features core functions such as flexible movement, height adjustment, and free rotation, making it suitable for various office scenarios.

1. Structure and Classification
The structure of a swivel chair 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 two types:

• Semi-swivel chair: With a left-right rotation range of 90 degrees, it is suitable for scenarios with limited space or where only minor adjustments are needed.
• Full-swivel chair: Supporting 360-degree rotation, it meets the need for all-around movement and is commonly found in open office areas or conference rooms.

2. Core Functions and Principles

• Flexible movement: Equipped with universal wheels at the bottom, a swivel chair allows easy access to all corners of the office area without moving the body, reducing the number of times one needs to stand up and enhancing work efficiency.
• Height adjustment: Achieved through a gas lift, which is filled with high-pressure nitrogen gas inside. The difference in piston cross-sectional areas generates elastic force to support body weight and adjust seat height, with some models allowing locking at any position.
• Free rotation: The rotation function originates from a spherical valve at the bottom, composed of three iron pieces and steel balls. When seated, the valve enables low-friction rotation through the cooperation of steel balls and iron pieces, allowing various comfortable postures in combination with universal wheels.

3. Common Types and Application Scenarios

• Work chair: A basic model that meets daily office needs, focusing on cost-effectiveness.
• Staff chair: With a simple design, it is suitable for ordinary employee workstations and emphasizes durability.
• Mid-back/high-back chair: Equipped with more features (such as headrests and adjustable armrests), it is suitable for management or long-hour office scenarios, providing higher comfort.

4. Typical Case
Take the Deli 4901S ergonomic computer swivel chair as an example. Its installation components include the backrest, armrests, seat, gas lift, chair legs, base, and wheels. This model reduces fatigue from prolonged sitting through ergonomic design (such as lumbar support and adjustable headrest), and the combination of the gas lift and universal wheels further enhances the convenience of movement and adjustment.

Through structural optimization and functional innovation, swivel chairs have become a key tool for improving efficiency and comfort in modern office scenarios.
