Spine & Seat

Its stated method is “start from the problem, not the product.” For every candidate it pulls the published fit specifications — seat height range, seat depth, backrest height, lumbar adjustment type, weight capacity, warranty terms — and maps them against published anthropometric tables with the arithmetic shown, so a reader can redo the working rather than take the conclusion. That is where its most practical page comes from: a lookup table that runs from your standing height to the seat height you need. Every specification links to the manufacturer's own figure, every chair is checked as currently sold before it is featured, and the date each one was verified is printed on the page.

It is unusually blunt about what it has not done. “We have not tested these chairs. No lab, no six-week trials, no measured pressure maps.” Where a specification is not published it says “not published” rather than estimating, on the principle that “an empty space is better than an invented one.” It claims no clinical standing — “we are not clinicians, not doctors, not physical therapists, not certified ergonomists” — in a category where the competition leads with exactly those credentials, and it carries no reviews, testimonials or star ratings because it has none. It refuses the category's central overclaim too: chairs redistribute load, they do not decompress nerves, reduce herniations or cure conditions, and the pain pages flag the symptoms that need a clinician rather than a chair. It prints no prices, because it runs no live price feed. Every pick has to say who it fits and who it does not, and the site's own position is that the second half is where most of the value is.

That is the same standard The First Buyer holds every site in the portfolio to, which is why Spine & Seat is here. It is owned and edited by the same person, Michael W., under the same rules: no payment for placement, no brand input into a page, and Amazon commission that, in the site's own words, “does not change your price and it does not change the order of the picks.” Health-adjacent buying is the easiest place in retail to imply a qualification nobody checks, which is exactly why this site prints the qualifications it does not hold and the tests it has not run. Nothing bought its way onto this list and nothing could — the portfolio is an inventory of what one publisher answers for.
