Source policy

We prefer official documentation, manufacturers, recognised professional bodies, regulators and other primary sources for factual claims. Product availability, specifications and retailer destinations are rechecked before publication.

Match the document to the model

We look for model numbers, labelled dimensions, fitting diagrams and the relevant product revision. A specification for a similar-looking chair, desk or mounting arm may describe a different base, cylinder, top or fixing arrangement.

Article source sections link to the documents and guidance that support the advice. Internal research records retain the model and listing checks used during preparation.

Explain missing or conflicting information

A retailer title, a general product overview and a manufacturer’s drawing can use different reference points. We explain important differences, identify the source used and state which measurements still need confirmation. We do not fill a missing fitting limit with an assumed value.

Workstation advice may also refer to recognised professional bodies and regulators, including the Health and Safety Executive. These references support the relevant guidance; they do not imply endorsement of a product.

Keep the limits of a check clear

A guide’s visible update date uses month and year. It records the article review rather than a promise that stock, pricing or every external document remains unchanged.

When reliable evidence changes an important fact, we revise the affected advice. The editorial policy sets out the standards for recommendations and source use.
