Slouching isn't an option here — and that's exactly the point. The Jari ActivStool's rotating convex base forces constant micro-movements that keep you focused and engaged, whether you're at a desk, in a study group or collaborative learning space. Gas-height adjustment spans 400–500mm, so one stool works across a huge range of users in NZ classrooms, libraries and open offices. Lightweight polypropylene seat, slip-resistant base, 110kg load capacity. Choose from four colours: Blue, Red, Yellow, or Green seat with White base. Delivered assembled.
