We distinguish general material knowledge from manufacturer information. Sources are listed in each guide. A statement about a fibre is not automatically evidence of an effect of a finished duvet, pillow or mattress.

What do we use the sources for?

Scientific materials studies are used to explain matters such as fibre structure, wettability and compression. Human studies and professional guidance are used for sleep and allergies. For each source, we explain what the study is about and which questions it can help address.

A test of a needle-punched insulating layer is not a clinical test of a duvet. We therefore distinguish results that apply to the experimental sample from claims about a finished product. Manufacturer statements are not treated as independent studies.

Source base and limitations

The source base includes scientific materials studies, research on sleep and professional guidance on allergies. References in the individual guides link to publishers or bibliographic records in resources including Europe PMC.

The content is not a systematic literature review. Not all databases, languages, unpublished product tests or full texts are covered, and funding and conflicts of interest have not been assessed exhaustively. The cited sources do not establish better sleep or fewer allergy symptoms from untreated kapok bedding. This is not proof that such studies do not exist.

Editorial responsibility

Doas ApS is responsible for the content and publication and has a commercial interest in this product area. The website is not published by a research institution.

Phillip Dahlmann is the company's kapok specialist, with 15 years of experience working with the material. Practical experience complements the cited sources but does not replace scientific evidence. We distinguish material knowledge, practical experience and completed product tests.
