Nine hundred and eighty-two grams

Published to the gram, with a 200 kg rating alongside it. That combination — the lightest stool here and the highest load rating — is what makes this one stand out, and the materials list explains it: polypropylene with a steel tension spring doing the work.

Ten steps

The coarsest adjustment of the telescoping stools on this shelf, at roughly four centimetres per step. For most observing that is close enough; at high magnification, where the eye has to sit precisely behind a short eyepiece, a finer step is better.

The materials, named individually

Polypropylene for the stool, polyester for the strap, steel for the tension spring. Naming all three is unusual, and the spring is the interesting one — it is the part that carries the load.

The listing’s padding

The fifth bullet runs through pond, fishing, chair, picnic, portable, folding and step stool before mentioning the packaging. The figures are in the first four bullets and they are all usable.

Availability
