it is impossible to actually sit on a Jari Activstool, no lying back, no slouching and definitely no sitting still. With a rotating convex base Jari forms one leg of a stable tripod, your own legs provide the other two parts. That means you are constantly flexing, adjusting and moving; the ideal way to stay focussed and concentrate. But the coolest thing about Jari Activstool is that it is gas height adjustable. That means it fits a huge range of students and just about any application: • Classrooms • Libraries • Study groups • Open spaces • Collaborative learning • Behind a desk or on its own • Sizes: 305 x 400 – 500 (WxH) • Colours: Blue, Red, Yellow, White No longer do you need various sizes of stools to suit the range of your student population, Jari Activstool adjusts to suit almost everyone in a senior school environment, right up to adult size.
