What is published

Maximum seat height about 44.5 cm. Overall 44.5 by 25 by 25. Folded to about 6.5 by 25. Seat diameter about 25 cm. Load about 100 kg. Five figures, which is a genuine specification even if two of them are approximate.

The rating to think about

A hundred kilograms, where two stools on this shelf state two hundred. Observing is not sitting still: an observer leans towards an eyepiece, shifts weight and gets up and down repeatedly. Margin above body weight is worth more here than in a garden chair.

The folded size is the practical figure

Six and a half centimetres thick. That slides into the side of a case or down the back of a rucksack, which is what decides whether a stool is present on the night it is needed.

The step count that is missing

The maximum height is given and the number of positions is not. A stool with four steps across 38 cm is a different proposition from one with twelve, and this listing does not say which it is.

Availability

German, French, Italian and Spanish Amazon stores ran from 18 € to 28 € on the day of the survey.

American and British Amazon stores list it in local currency, which the euro range above sets aside.
