SitTight transforms sitting into an activity that improves your health, instead of damaging it, by using your body's natural ability to balance.Balancing on your center of gravity on a SitTight causes an increase in heart rate from the activation of core muscles, an increase in brain activity as the central nervous system controls those muscles and creates a sensation similar to riding a bike.Our innovative chair delivers FITNESS for your body, FOCUS for your mind and FUN for your spirit.
