Every fit figure is computed, from one cited table
Not "a good height for most people". Seat height from published popliteal-height percentiles, maximum seat depth from buttock-popliteal length, stool height from sitting elbow-rest height. One module produces all of them, so the site cannot contradict itself, and the source is named so you can check it.
Prices are live, dated, and expire on their own
Every figure comes from a lookup against the retailer, carries the date it was verified, and disappears after 48 hours rather than sitting on the page going stale. Where there is no live price you get "check price", never a remembered number.
Every pick states what is wrong with it
Not a hedge at the end - a required field on every product in our registry. And every roundup names at least one pick we recommend against, with the spec-based reason, because a shortlist with no exclusions is a catalog.
The gaps are published, not smoothed over
When a manufacturer does not publish a seat height, a capacity or a warranty term, we print that. Two otherwise-interesting stools sit on an excluded list for exactly this reason, and on several pages the missing figure is the most useful paragraph.
The score has a rubric one click away
Six criteria, each computable from published documentation, each one shown per pick. No unrubric'd decimals. Including cost per warranty year, which is arithmetic no competitor in the set we surveyed publishes.
We name who is better than us, and where
Publishers who own the units can tell you about all-day comfort, foam breakdown and build quality. We cannot. That list is published on the methodology page rather than left for you to discover.
