Office Chair

Office chairs are chairs equipped for the convenience of work in daily work and social activities, coming in various types and having installation and safety issues.

I. Definition and Classification of Office Chairs An office chair, in English, is an "office chair," a specialized seat designed to meet work requirements. According to their purposes, they can be divided into two categories: narrow and broad. Narrowly defined, they refer to backrest chairs used for desk work in a sitting position, emphasizing ergonomic design to support long hours of office work. Broadly defined, they encompass all chairs used in offices, including executive chairs (for senior management), staff chairs (for ordinary employees), conference chairs, etc., with functions focused on adapting to different scenarios.

II. Installation Precautions The installation steps for different models of office chairs vary, and it is essential to strictly follow the instructions or video guidance. For example:

1. 1011A Office Chair: Insert A and L screws and place gaskets. When installing the seat armrests, fix them first and then tighten them to avoid the risk of loose components.
2. 2022A Office Chair: Install the base casters, chassis (using screws J and K with gasket L), and armrests (requiring screws and sleeves) in sequence, and finally place them on the base. Key Points: The screw specifications must match, and gaskets can reduce metal friction and prevent structural damage.

III. Safety Issues and Recall Cases Quality hazards in office chairs can lead to serious consequences, and several recall incidents in recent years have exposed industry risks:

1. March 2023: The United States and Canada recalled office chairs made in China due to the risk of backrest breakage, resulting in 12 reports (including 10 injuries). The breakage may be caused by insufficient material strength or design flaws.
2. September 2024: The State Administration for Market Regulation of China found 15 batches of non-compliant products during inspections, with stability issues being prominent, such as base center-of-gravity shift and the risk of gas spring explosions (it is necessary to choose gas springs certified by SGS).
3. January 2025: The United States recalled WorkPro Momentum office chairs made in China due to the risk of falls caused by bolt failure (7 reports including 2 minor injuries). Bolt loosening may be due to improper installation or material fatigue.

IV. Purchase and Usage Recommendations

1. Give priority to products certified by BIFMA (Business and Institutional Furniture Manufacturers Association) or GB/T 38607-2020 (Chinese office chair standard) to ensure that materials, structure, and stability meet standards.
2. Regularly inspect components such as screws, gas springs, and casters, and replace them immediately if looseness or wear is found.
3. Avoid overloading (usually, the weight limit of office chairs is 100-130 kg) to prevent structural deformation.
