Evidence and scope
We prefer public information from occupational-safety authorities, standards organizations, manufacturers’ technical documents, and other primary sources. We distinguish general selection guidance from medical advice.
No invented testing
We do not say a chair was tested, reviewed in person, or recommended by a professional unless that is true and documented.
Changing information
Standards, model specifications, warranties, prices, and product availability can change. Readers should verify current documentation before purchase.
Corrections
Material factual corrections may be submitted through the restricted-purpose contact page.
