How We Choose
We haven't slept on these products, and we don't pretend to have. Here is exactly what we do instead — and it's checkable.
Most mattress roundups lead with “we tested” and hope you don’t ask how. We take the opposite approach: we state plainly that we have not slept on the products we compare, and we compete on a method that doesn’t need a lab — reading each product’s published specs and stated certifications against the evidence, transparently and reproducibly. If you followed our steps with the same listings and the same research, you should reach the same conclusions.
1. We start from the specs, not the marketing
Every product is evaluated on what its listing and the maker’s published line actually state: the construction (memory foam, hybrid, coils), the firmness, the profile height, the trial and warranty, and whether the listing states a fiberglass-freebuild. Each of those facts is read from the listing on a dated visit, and that date is shown on the page. Where a listing does not state a figure — which is common for firmness and the fiberglass position — we print “Not published.”That empty cell is a finding, not a gap in our research: a maker that won’t state it is telling you something.
2. We record the certifications and explain their scope
For each pick we record the third-party certifications the maker publishes — CertiPUR-US, OEKO-TEX Standard 100, GREENGUARD Gold, and the organic standards GOTS and GOLS — and then we explain, honestly, what each one actually audits and what it leaves out.This is the part the field skips. CertiPUR-US certifies the polyurethane foam only, not the whole mattress, and says nothing about fiberglass. OEKO-TEX certifies the textile that was submitted. Only the organic standards (GOTS/GOLS) prohibit a fiberglass fire barrier in what they certify. We link the certifying body for every claim so you can verify a specific product yourself — see the full Certification Decoder.
One honest limit: we record what each maker publishes. We do not independently re-audit each unit against the certifying body’s database — that’s why every product page tells you to verify a specific unit with the body, and links you to it.
3. Every evidence claim is cited
When we say the evidence favors a medium-firm mattress for lower back pain, that claim links to a published source — the Kovacs randomized trial in The Lancet, the Radwan systematic review in Sleep Health, or consumer-health guidance. We don’t assert benefits on our own authority, because we haven’t earned that authority; we point you to the people who have.
4. Rankings are argued, not scored
We deliberately do notput a numeric score on these products. A score implies a measurement we didn’t take — we own none of these units. Instead, each roundup ranks its picks in prose, explaining who each one suits and, just as often, who should skip it. Where a cheaper certified pick beats a pricier one for the buyer, the cheaper one wins, regardless of commission.
5. Prices are live, dated, and allowed to expire
Every price on this site comes from a live Amazon data feed, refreshed daily and stamped with the date it was pulled. We never type a price into the site by hand. If the daily refresh stops, prices don’t go stale — they disappear, and the button falls back to “Check price on Amazon.” The failure mode is silence, not a wrong number.
What we will never do
No invented sleep trials, no fabricated star ratings or testimonials, no borrowed credentials, and no claim that a certification covers something it doesn’t. Products we claim to have tested: zero — and we say so. What we bring instead is a habit of reading the fine print and the certifying body’s own rules, and reporting them straight. Our editorial policy covers corrections and update cadence.
