Overview
A 9 inch mini exercise ball made from anti-burst, slightly textured PVC, designed for core training, physical therapy, and stretching. It inflates with an included straw rather than a pump and comes backed by a 30 day return window and 12 month warranty.
The small size is the point here: it is meant for targeted core and PT work rather than full-body stability exercises like a standard large stability ball. Reviewers most often bought it for physical therapy sessions specifically, and its grip texture gets called out repeatedly as staying in place during exercises rather than sliding.
- 9 inch diameter, anti-burst PVC
- Slightly textured, non-slip surface
- Inflates with included straw, no pump required
- 30 day returns, 12 month warranty
Who it's for
Good for anyone doing physical therapy, arthritis-related stretching, or targeted core and Pilates work at home. Less suited to anyone wanting a single ball for full-body stability training, which needs a larger size.
What buyers say
From Amazon customer reviews.
Reviewers bought this most often for physical therapy, arthritis-related stretching, and Pilates core work, and repeatedly praise the textured surface for staying grippy and in place during exercises. Inflation with the included straw is called easy by most, though one reviewer found it difficult to fully seal the plug afterward despite the ball holding air well in practice.
Strengths and trade-offs
Drawn from this product's published specifications.
- Textured surface grips and stays in place during exercises
- Compact size suits targeted core and PT work
- Holds inflation well over repeated use per reviewers
- Plug can be difficult to fully seal after inflation
- Too small for full-body stability or standing balance work
Performance notes
The textured PVC surface is designed to grip rather than slide during exercises, which multiple reviewers confirm holds true in use, including for arthritis-related stretching where a stable ball matters. Inflation is done with the included straw rather than a pump, which most reviewers found easy, though at least one found fully sealing the plug after inflation difficult.
