Sitting and standing are both bad if you do either for long enough, and the useful position is somewhere between the two. A leaning stool puts you there. The seat here rises from 23.6 in to 33.3 in off the floor, which means it works at a conventional desk at the low end and at a full standing desk at the top, and the transition takes a second. The seat measures 16.1 in deep by 15 in wide and is padded with foam under a polyester cover. That size is intentional. A seat wide enough to settle into defeats the purpose, because the benefit of a perch comes from keeping your hip angle open and your weight partly on your feet. A narrower seat holds the posture without you having to think about maintaining it. Underneath, a polypropylene and steel construction carries a static load of 264 lb, and the whole stool weighs 19.6 lb, which gives it enough mass to stay put when you lean into it while still being easy to reposition..
