Overview
Trideer's 9-inch mini exercise ball is sized for physical therapy and pilates work, made from anti-burst PVC with a textured, non-slip surface.
It's positioned for rehab exercises targeting the ankle, knee, hip and shoulder, as well as added core stability work in pilates, barre or yoga. The ball inflates through an included tube and stores easily given its small footprint.

Who it's for
Fits physical therapy patients and pilates or barre practitioners who want a small stability tool rather than a full-size seated exercise ball. Less useful for anyone looking for a large ball to sit and bounce on.
