Office Chair, Swivel Chair, Staff Chair
Office chairs, swivel chairs, and staff chairs are categories of office seating with an inclusive relationship, where staff chairs are a็ปๅ็ฑปๅ (sub-type) of swivel chairs, and swivel chairs are a common functional branch of office chairs. The following provides an explanation from the perspectives of definitions, structures, functions, and typical characteristics:
1. Definitions and Category Affiliations
Office chairs are general terms for seating used in office settings, encompassing various functional designs. Swivel chairs are a sub-type of office chairs with a rotating seat function, known as swivel chairs in English, and they belong to the category of office chairs or computer chairs. Staff chairs, on the other hand, are a series designed for general office staff within the swivel chair category, typically featuring low backrests and no armrests, and they are a sub-category of office swivel chairs. For example, the Deli 4901S ergonomic computer swivel chair is clearly labeled as a "staff chair," indicating that it meets both the functions of a swivel chair and the positioning of a staff chair.
2. Structural Feature Differences
The core structure of a swivel chair includes a headrest, backrest, seat, armrests, gas lift support, a rotating shaft, and a five-star base with wheels, with some models equipped with adjustable headrests or lumbar supports. Staff chairs, as simplified versions of swivel chairs, typically omit the headrest and armrests, with a reduced backrest height to save space, while retaining basic functions such as gas lift height adjustment, 360-degree rotation, and a five-star base. Taking the Deli 4901S as an example, its components include a backrest, armrests, seat, gas lift, etc., indicating that staff chairs can optionally be equipped with armrests, but their overall design remains lightweight.
3. Functional Implementation Principles
The height adjustment function of swivel chairs relies on gas lifts, which generate elastic force through the difference in piston cross-sectional areas and internal high-pressure nitrogen gas to support body weight and achieve height adjustment, which can be locked at any position. Although staff chairs have simplified structures, they also use gas lift technology to ensure basic height adjustment and rotation needs. Some high-end staff chairs incorporate ergonomic designs, such as the Deli 4901S, which enhances long-term sitting comfort through a่ๅจ็ปๆ (linked structure) between the base and backrest.
4. Applicable Scenarios and Selection Recommendations
Swivel chairs, with their comprehensive functions, are suitable for scenarios such as management offices and conference rooms where frequent adjustments to sitting posture are required. Staff chairs, on the other hand, are preferred for open office areas or general workstations due to their lower cost and smaller space occupation. When selecting, attention should be paid to gas lift safety certifications (such as SGS and BIFMA standards), chair wheel materials (nylon wheels are suitable for carpets, while hard wheels are suitable for tiles), and backrest support to ensure long-term health and durability.
