Swivel, Computer, and Office Chairs

Swivel chairs, computer chairs, and office chairs are types of seating that are related but have different functional focuses. Swivel chairs are a subcategory of office chairs or computer chairs. Computer chairs are functional seats specifically designed for office or study scenarios, while office chairs encompass a variety of seating types suitable for office settings.

Core Features and Classification of Swivel Chairs

The English name for a swivel chair is "swivel chair." Its core feature is that the seat can rotate, achieving a 90-degree (semi-swivel) or 360-degree (full-swivel) rotation through a rotating shaft. Its structure typically includes a headrest, backrest, seat, armrests, gas-lift support, rotating shaft, and a five-star base with wheels. Among these components, the gas spring is the core part for height adjustment: the high-pressure nitrogen inside generates elastic force through the difference in piston cross-sectional areas, supporting human weight and adjusting height, and can be locked at any position. For example, in the installation process of the Deli 4901S ergonomic computer swivel chair, the gas spring needs to be inserted into the chair foot, and then the chassis is used to connect the seat, which precisely utilizes the gas spring to achieve the coordinated function of height adjustment and rotation.

Functional Positioning and Design Standards of Computer Chairs

Computer chairs are seats specifically designed to relieve fatigue from prolonged sitting, adapted to office and study scenarios through ergonomic design. Their functional standards include:

• Adjustability: The headrest, lumbar support, and armrests should support multi-dimensional adjustments (such as height, forward and backward movement, and angle) to fit users of different body types;
• Safety: A thickened explosion-proof steel plate should be equipped under the seat cushion, and the gas spring should pass SGS international certification to prevent the risk of gas spring explosion;
• Material and Load-bearing: The fabric covers materials such as hemp, mesh, and leather. The chair feet are made of nylon or aluminum alloy structures and need to meet dynamic load-bearing standards (such as over 100 kg). Taking the Deli 4901S as an example, its backrest, armrests, and seat all support independent adjustments, and the gas spring has passed SGS certification, meeting the core requirements of an ergonomic computer chair.

Scenario-based Classification of Office Chairs

Office chairs are a general term for seats suitable for office scenarios. They are classified according to function and hierarchy as follows:

• Work chairs/staff chairs: Basic models that meet daily office needs, with a structure similar to that of swivel chairs;
• Mid-back chairs/executive chairs: Dedicated for management, with higher backrests and more premium materials (such as genuine leather), and some are equipped with electric adjustment functions;
• Computer chairs: As a subcategory of office chairs, they emphasize ergonomics and comfort for prolonged sitting. Due to their rotating function, swivel chairs are often classified as "work chairs" or "staff chairs" within office chairs, while computer chairs, due to their special functionality, can exist independently of traditional office chair classifications.
