What Is a Stability Ball Chair?
A stability ball chair is a type of desk chair that uses a stability or exercise ball as the seat cushion. Some people simply use large exercise balls as a desk chair, as opposed to a designated stability ball chair; however, an actual exercise ball chair will typically feature a stability ball mounted on casters, similar to any other rolling desk chair, with a support bar for the lower back. There are arguments for and against the use of these chairs.
