Define the reader decision
Each page starts with one sourcing question, such as density, height, compliance scope, packaging recovery or factory qualification.
This policy explains the team behind our sourcing guides, the evidence hierarchy we use, the claims we limit and how readers can request a correction. It does not turn commercial content into independent medical, legal or certification advice.
SensaRest Product Engineering is the collective organizational byline for content created from the company’s product-development and manufacturing perspective. It covers input from product specification, structural design, foam and cover development, process control, sampling, packaging and commercial teams where relevant. The byline does not represent a named clinician, independent laboratory or regulatory adviser, and the site does not invent individual credentials. Articles explain how OEM buyers can define, sample and verify a pillow program; they do not diagnose a sleeper or guarantee a health outcome. When a page discusses a certification, test method or material claim, readers should verify the current issuing body, tested sample, scope, date and destination-market requirement. Order-specific documents and approved samples take priority over general web copy.
A document is useful only when its holder, sample, scope, method and date match the statement being made.
| Priority | Evidence type | How we use it |
|---|---|---|
| 1 · Order-specific | Approved sample, purchase specification, current report and production record | Controls what is supplied and what the buyer may claim for that SKU |
| 2 · Primary authority | Official program owner, standards body, regulator or test-procedure publisher | Defines program scope, terminology and current requirements |
| 3 · Controlled factory evidence | Internal process records, sampling observations and QC checks | Explains repeatability and manufacturing decisions without replacing third-party proof |
| 4 · Secondary research | Market reports, review patterns and buyer-question analysis | Forms a design hypothesis; it is labeled and validated before becoming a product claim |
Each page starts with one sourcing question, such as density, height, compliance scope, packaging recovery or factory qualification.
Measured specifications and official definitions are stated as facts. Design directions, market observations and buyer preferences are labeled as context or hypotheses.
Certification, cooling, antibacterial, low-odor and durability language must identify the relevant material, sample or validation route instead of implying universal coverage.
Guides connect readers to the relevant product, specification tool, quality page, official source or sample request rather than ending with an unsupported conclusion.
Publication and material update dates are shown. Substantive corrections update the page, structured data and sitemap date together.
Send the page URL, the exact statement and the evidence you believe should replace it through the contact page. We review factual errors, outdated program scope, broken sources, translation issues and material claim mismatches. Commercial disagreement alone is not treated as a factual correction, but it may trigger clearer wording.
