Office Chair Staff Chair Swivel

Staff chairs (office chairs for employees) in office chairs usually have a swivel function and belong to the category of swivel chairs. Their design is centered around meeting daily office needs, with the following specific features:

1. Swivel Function Characteristics
The swivel function of staff chairs is mainly 360-degree omnidirectional rotation, enabling free rotation without dead angles. This facilitates quick access to files, communication with colleagues, or adjustment of sitting posture direction. Some models have a semi-rotation design (90 degrees to the left and right), but such products are relatively rare, with the mainstream still focusing on full-rotation functions. The rotation process should remain smooth without stuttering, which depends on the precise design of the swivel shaft structure and the wear resistance of the materials. For example, the use of high-strength bearings or thickened steel swivel plates ensures stable rotation even after long-term use.

2. Structural Composition and Function Realization
The swivel function of staff chairs is achieved through the collaboration of the swivel shaft and the five-claw base with wheels. The swivel shaft, located between the seat and the gas lift, is the core component for rotation and needs to withstand the friction and pressure caused by frequent rotation. The five-claw base is usually equipped with universal wheels, supporting multi-directional movement and further enhancing flexibility. In addition, the gas lift support system (which achieves height adjustment through high-pressure nitrogen) combined with the swivel shaft allows staff chairs to meet both height adjustment and rotation needs simultaneously. For example, the Deli 4901S staff chair adopts such a design, supporting a height adjustment range of 5cm-10cm and 360-degree rotation.

3. Applicable Scenarios and Classification Expansion
Staff chairs belong to the series of office chairs for employees and are mainly designed with low backrests, no armrests, or simple armrests, suitable for open office areas or compact workstations. According to differences in backrest height and function, swivel chairs can also be further classified as follows:

• Work chairs: Medium backrests, equipped with adjustable armrests, suitable for long periods of focused work;
• Mid-back manager chairs: High backrests with reinforced lumbar support, suitable for middle management positions;
• Executive chairs: High backrests + headrests, mostly made of genuine leather or mesh fabric, with comprehensive functions (such as tilt locking and multi-level adjustment), suitable for high-level office scenarios.

4. Purchase Considerations
When choosing staff chairs, the following aspects should be given priority attention:

• Quality of the gas lift: Prioritize products that have passed international certifications such as SGS and BIFMA to avoid safety hazards caused by gas lift explosions;
• Smoothness of the wheels: PU silent wheels can reduce floor scratches and noise, suitable for wooden floors or carpeted environments;
• Comfort of the sitting experience: The seat cushion should be made of high-density foam or breathable mesh fabric, and the backrest should conform to the ergonomic curve to reduce fatigue from prolonged sitting.
  In terms of price, staff chairs have a wide range (from tens of yuan to thousands of yuan). It is recommended to choose products with functions that match the budget. For example, a basic model that meets rotation and height adjustment requirements is sufficient, while a high-end model can add additional functions such as lumbar support and headrests.
