Overview
A 9-inch inflatable mini exercise ball made from thickened, non-toxic PVC with a honeycomb texture for grip, rated to hold up to 220 lbs. It's built for Pilates, barre, physical therapy, and core work rather than full-size stability ball exercises.
At this size the ball is meant to be held between the knees or thighs for adductor and core engagement, or tucked behind the lower back as lumbar support while sitting. A physical therapist reviewer specifically named it as the ball they recommend to patients for trunk stabilization work, which lines up with how the product is marketed.
- 9-inch diameter, non-toxic PVC construction
- Honeycomb texture rated to 220 lbs
- Includes straw, plug, and plug puller
- Inflates without a separate pump
Who it's for
Fits anyone doing Pilates, barre, or physical therapy exercises that call for a small squeeze ball rather than a full stability ball. Also works as a portable lumbar support for a desk chair.
