Common Classifications and Definitions of Office Chairs

Office chairs are seats designed to meet daily work requirements. In a narrow sense, they refer to backrest chairs used for desk work in a sitting position. In a broad sense, they cover all types of seats in an office, such as executive chairs (for senior management), staff chairs (for ordinary employees), and conference chairs. Different types of office chairs vary in functions, materials, and prices. For example, executive chairs are usually equipped with headrests, adjustable armrests, and thicker cushions, while staff chairs focus more on basic support and cost-effectiveness.

Quality Issues and Safety Risks to Be Alert To

In recent years, many countries have issued recall notices for office chairs mainly due to safety hazards:

• In March 2023, the United States and Canada recalled some office chairs made in China because the backrests might break, causing users to fall;
• In September 2024, the State Administration for Market Regulation of China found that 15 batches of office chairs were unqualified in a spot check. Stability issues (such as insufficient load-bearing capacity of chair legs and failure of the tilting mechanism) were the most prominent;
• In January 2025, the United States recalled WorkPro Momentum office chairs made in China because the bolts might fail, posing a risk of falling. Advice: When purchasing, give priority to products that have passed certifications from BIFMA (Business and Institutional Furniture Manufacturers Association in the United States) or GB/T 38733-2020 (the national standard for office chairs in China), and regularly check whether components such as chair legs, gas cylinders, and bolts are loose.

Key Points for Selecting Ergonomic Office Chairs

To address the problem of back fatigue caused by prolonged sitting, ergonomic office chairs improve the experience through scientific design. The following aspects should be the focus:

• Lumbar and back support: Give priority to products with adjustable lumbar supports. For example, the Sihoo C500I second generation achieves AI intelligent support through inflatable airbags and dial control, while cost-effective models like the SumLush Xia Muwu Fit CC provide zoned pressure dispersion;
• Cushion support and seat depth: The front edge of the cushion should have a waterfall design to avoid pressing on the thighs. The seat depth should be adjustable to accommodate people of different heights (it is recommended that the seat depth match the length of the lower legs);
• Adjustment range and stability: The headrest, armrests, and the backrest's reclining angle should support multi-level adjustments. The gas cylinder should pass SGS or TUV certification (with a load-bearing capacity of ≥113 kg). It is recommended to choose a five-star base + silent wheel combination for the chair legs.
