Foshan Office Chair Quality Standards

For the quality standards of office chairs in Foshan, reference can be made to the 'Foshan Standard for Office Chairs' (t/fss x—2021). This standard provides detailed regulations on various aspects of office chairs and is applicable to indoor work chairs. Chairs with similar uses in other settings can also refer to it for implementation.

In terms of main dimensions: The seat height should be between 400 and 515 millimeters. This range can meet the sitting posture needs of people of different heights and ensure comfortable leg placement. The seat depth is between 400 and 540 millimeters. An appropriate seat depth allows the user's back to be well-supported. The seat width should be greater than or equal to 430 millimeters to provide sufficient space for the buttocks. The lifting stroke should be greater than or equal to 60 millimeters, facilitating users to adjust the seat height according to their own needs. The inner width of the armrests should be greater than or equal to 460 millimeters to ensure natural arm placement. The armrest height should be between 160 and 300 millimeters to adapt to different usage scenarios and arm postures. In addition, other dimensions should comply with the requirements in Section 5.1 of qb/t 2280 - 2016.

Regarding shape and positional tolerances: They should comply with the requirements in Section 5.2 of qb/t 2280 - 2016. This ensures the shape and positional accuracy of the various components of the office chair, making the overall structure of the chair stable and ensuring good cooperation between components without issues such as looseness or skewness that could affect the user experience and safety.

In terms of appearance: It should comply with the requirements in Section 5.3 of qb/t 2280 - 2016. The office chair should have no obvious flaws, with a flat and smooth surface, uniform color, and no scratches or cracks. This not only relates to the product's aesthetics but also reflects its manufacturing process and quality level.

Regarding physicochemical properties: Items such as density, foam plastic, textile fabric, leather, resilience, and 75% compression set should comply with the requirements in Table 2. These physicochemical property indicators directly affect the comfort and durability of the office chair. For example, an appropriate density and resilience can ensure the softness and support of the seat, preventing users from feeling fatigued after sitting for a long time. Good-quality textile fabric and leather can improve the chair's abrasion resistance and stain resistance, extending its service life.
