Formaldehyde in Folding Office Chairs

Folding office chairs may pose a risk of formaldehyde exceeding standards. The sources, risks, and countermeasures are as follows:

1. Main sources of formaldehyde
The formaldehyde in folding office chairs primarily comes from the paint sprayed on the surface of metal substrates and the leather adhesives. The paint may contain formaldehyde-containing solvents or curing agents, while leather adhesives (such as urea-formaldehyde resins) release formaldehyde during the curing process. Additionally, if the chair uses low-quality boards (such as medium-density fiberboard or particleboard) as auxiliary materials and lacks effective edge sealing, formaldehyde from within the boards will continue to be released.

2. Risks of formaldehyde exceeding standards
According to sampling inspection data from the State Administration for Market Regulation, the non-compliance rate for some batches of office chairs is as high as 23.3%, with formaldehyde exceeding standards being one of the main issues. Excessive formaldehyde can cause short-term symptoms such as eye irritation, sore throat, and dizziness. Long-term exposure may increase the risk of diseases such as leukemia and nasopharyngeal cancer. It is important to note: Even if the overall formaldehyde concentration in office furniture is not high, if the environmental protection grade of local materials (such as leather or paint) is low, there may still be a risk of local exceeding standards.

3. Differences between qualified and unqualified products
Qualified folding office chairs that meet national standards must use production materials that have passed environmental certifications (such as China's E1 grade or the EU's CE certification) and have undergone complete process treatments (such as tight edge sealing and thorough paint curing). The formaldehyde emission is usually controlled within a safe range (≤0.124mg/m³). In contrast, unqualified products may use materials with high formaldehyde content or cut corners (such as reducing the number of edge sealing layers or using low-quality adhesives) to reduce costs, resulting in excessive formaldehyde emissions.

4. Traps consumers need to be wary of
Some merchants may tamper with inspection reports, marking 'formaldehyde non-compliance' as 'compliance', or mislead consumers through false advertising. When purchasing, it is recommended to choose reputable brands, check whether the product comes with a complete inspection report (such as CMA certification), and verify the formaldehyde emission data in the report.

5. Suggestions for reducing formaldehyde risks
It is recommended to place newly purchased folding office chairs outdoors or on a balcony with good ventilation for 3 days to 1 month until the odor has largely dissipated before use. If possible, use activated carbon packs or air purifiers to accelerate formaldehyde volatilization. If a persistent pungent odor or physical discomfort occurs during use, stop using the chair immediately and contact the merchant for resolution.
