Inspection of Office Chairs

The inspection conducted by the State Administration for Market Regulation revealed that the non-compliance rate of office chairs was 14.9%, with major issues focusing on stability, caster wear, and formaldehyde emissions.

I. Overall Inspection Overview
This inspection covered 101 batches of office chair products produced by 101 enterprises nationwide, identifying 15 non-compliant batches with a non-compliance rate of 14.9%. This data indicates that some office chair products on the market have quality risks, and consumers should be vigilant.

II. Major Non-compliant Items and Their Hazards

1. Non-compliant Stability: Seven batches of products had this issue, representing the highest proportion of non-compliance in this inspection. Stability is a core indicator for assessing office chair quality. If non-compliant, the chair is prone to tipping over when the user leans forward, backward, or sits sideways, potentially causing falls, fractures, and other accidents, especially posing higher risks to children or individuals with mobility impairments.
2. Non-compliant Caster Wear: Five batches of products failed this test. Casters are crucial components for the mobility of office chairs. If they lack wear resistance, they are prone to jamming or breaking after prolonged use, leading to不畅 (不畅 can be translated as 'impaired movement' or 'difficulty in moving') movement or sudden tipping of the chair, affecting safety.
3. Non-compliant Formaldehyde Emissions: Four batches of products had excessive formaldehyde levels. Formaldehyde is a common harmful gas, and long-term exposure can trigger respiratory diseases, allergic reactions, and even increase the risk of cancer. As office chairs are frequently contacted furniture, excessive formaldehyde emissions directly endanger the health of users.

III. Special Issues with Swivel Office Chairs
Swivel chairs have a complex structure and a higher failure rate of components. For example, the five-star base (support base) of some products broke during static load tests, indicating insufficient load-bearing capacity. Additionally, five batches failed the caster wear test, further highlighting the inconsistent quality of swivel chair components.

IV. Purchase Recommendations
When purchasing office chairs, consumers should prioritize products that have passed national mandatory certifications (such as CCC certification) and pay attention to stability test reports. Avoid chairs with pungent odors to reduce formaldehyde risks. For swivel chairs, check the firmness of components such as the five-star base and casters to ensure safety.
