The Stitz leaning aid is an exceptional piece of furniture, that involves neither sitting nor standing, but somewhere in between. What is so ingenious about Stitz, is that it allows the body to relax but puts it through its paces at the same time. Which is why you do not sit on Stitz, but rest on it at a slant. As a result, your pelvis adopts an upright position, your metabolism improves, your sense of balance is enhanced and your muscles are activated without subjecting them to too much strain. You can sit on the round seat from all sides.
