From Daniel Vladeta D.O., the creator of Oov, comes the latest technology in posture control, core stabilization and strengthening — the Balansit®. How can you "exercise" while sitting? Unstable devices activate your Core and require user to continuously maintain neutral position. The patented Balansit is a dynamic and active-sitting device. Sizes small, medium and large (see sizing chart on product page.)

Balansit improves posture and helps us breathe better… and diaphragmatic breathing helps reduce stress & improve concentration
