A stool that cannot agree on its own weight

One and a half kilograms in the title; one thousand one hundred and sixty grams in the fourth bullet. That is a difference of a third, on the specification that decides whether it gets carried. Both figures are printed above.

The mechanism

A spring that engages each of eleven steps. That gives an audible click when a height locks, which matters more in the dark than the number of steps does — sitting down on an unlocked stool is the failure mode this whole category has.

What it is missing

A load rating. Three stools on this shelf publish 180 or 200 kilograms; this one says it carries an average adult. That is a description, not a specification.

The rest of the listing

Written as second-person sales copy — tired of standing, sore feet, ideal for children. The figures that survive are eleven steps, forty-five centimetres, a twenty-five centimetre seat, and two contradictory weights.

Availability

German, French and Italian Amazon stores ran from 35 € to 54 € on the day of the survey.

Spanish Amazon store stood above 1.6× the cheapest country. A gap that size normally means stock forwarded from abroad rather than a seller on the ground, so that figure is left out of the range above.

British Amazon catalogue holds a record for it that nobody is selling.

American Amazon store gave no result whatever, so the buy button there opens a search rather than an empty page.

Figures as Keepa reported them on the day this page was last updated. Stock and pricing shift without warning.
