Sleep products are sold with a great deal of confident language and very little disclosed evidence. Foam densities that appear in marketing but not in specifications. Comfort described in adjectives. Health benefits implied strongly enough to be heard, worded carefully enough to be deniable.
InsideBedroom’s fact-checking exists to keep that language out of our articles, including when it would be commercially convenient to let it through.
Three things we will not do
We do not describe testing we did not perform. If we have not slept on a mattress, we do not say how it sleeps. Articles are explicit about whether a judgment comes from hands-on use, from published specifications, from owner reports at volume, or from an independent test we are citing. A roundup built on specifications is labeled as one.
We do not make medical claims. Sleep touches health, and that is exactly why we stay on our side of the line. We will report what a mattress is made of, what a manufacturer states, and what published research says with its citation attached. We will not tell a reader that a product will fix their back pain, their apnea, or their insomnia. Where a reader’s problem sounds clinical, the article says to speak to a clinician, and it says it plainly rather than as a disclaimer nobody reads.
We do not launder marketing into fact. A brand’s claim is reported as that brand’s claim, named and attributed. It does not become a neutral statement by being repeated in our voice.
What a claim has to be backed by
Product specifics come from the manufacturer’s own specification, not a retail listing and not a competitor’s comparison table. Dimensions, materials, layer construction, densities, certifications, warranty terms, and trial periods are all read from the source that is accountable for them.
Certifications are verified against the issuing body’s register where one is public. A certification mark is a checkable fact, and we check it rather than repeating the badge.
Research claims cite the study, with its population and its limits described. A finding in a small trial is reported as a finding in a small trial.
Prices carry the date we checked them, because they move constantly. We do not present a promotional price as a standing one.
Owner-reported experience at scale is useful and we use it, described as what it is: a pattern in reviews, not a measurement.
The verification sequence
Sources are captured before writing, kept verbatim with their URLs and retrieval dates. Every factual sentence in the draft is bound to its evidence, and an unbound one blocks the article.
Automated checks then confirm figures against sources, arithmetic, quotations, and date consistency. A judgment pass follows, asking whether the source truly supports the sentence: a specification for one size does not describe another, and a warranty term for one region does not apply everywhere.
A named InsideBedroom reviewer, never the article’s author, reads the finished piece and is credited on it. The verification record is archived against the article.
Where the commercial relationship sits
InsideBedroom earns commission when readers buy through our links. That is how the site is funded, and pretending otherwise would undermine everything else on this page.
What commission does not do is decide anything. It does not change which product wins a roundup, alter a rating, keep a flaw out of an article, or determine what we choose to cover. Commission rates are not an input to our recommendations, and a product with no affiliate programme competes on identical terms. Where we recommend something, the reasoning is in the article and the sources are cited so a reader can weigh it themselves.
Where a brand supplies a product for testing, the article says so.
Keeping articles current
Every article carries the date a person last reviewed it.
Products are discontinued, reformulated, and repriced constantly, so recommendations are re-checked on a schedule rather than when a reader emails. When a recommended product is no longer available or no longer the right answer, the article is updated or retired. We do not leave a dead recommendation standing because it still ranks.
Corrections
If a specification is wrong, a price is stale, or a product has changed, tell us through the contact page. We respond to every report, correct the article, note what changed, and update the verification record.
