Best Pilates Ball
(2026): 6 Picks, Mini to Stability

Balanced Body is one of the best-known names in studio Pilates equipment, and this 12-inch inflatable ball is sold on Amazon by Balanced Body Inc. itself: the manufacturer, not a reseller. It is the prop to buy if you want a small ball from a brand that makes studio apparatus: use it between the knees for bridges and inner-thigh work, behind the back for supported curl-ups, or under the upper back for thoracic extension.

Bala is a design-led barre and Pilates brand (best known for its Bangles), and its small non-weighted Pilates ball is sold on Amazon by Bala Bangles directly. Functionally it does the same job as any mini ball (squeezes, supports and feedback during mat work) so the reason to choose it is the look. If your props live out in the open and you care how they sit alongside the rest of your kit, this is the pick.

A 9-inch mini ball for under $10, sold by ProBody Pilates. It covers the same core uses as the pricier picks above (inner-thigh squeezes, ball-supported bridges and thoracic extension) at a third of the price. If you just want to try small-ball work at home before spending more, start here.

If you need the full-size stability ball rather than a mini ball, this 65cm gym-grade ball from ProBody Pilates is the pick. A stability ball is a different tool entirely: it is for roll-outs, pikes, supported back extension, hamstring stretches and seated balance work. Sizing matters, 65cm is a common middle size, so check it suits your height before ordering.

Rather than a ball on its own, the Byrex kit bundles a Pilates ring, a 10-inch mini ball, resistance bands and sliding discs for $24.99 (sold by ByrexLtd). That makes it the best value if you are building a home mat setup from scratch and want the main small props in one order. It does not include a large stability ball: pair it with the ProBody 65cm ball above if you want both.

To be clear up front: the BOSU is not a classical Pilates prop. It is a 26-inch half-dome balance trainer, sold here by Amazon.com, and it is widely used in Pilates-fusion classes and balance-focused workouts. If you already own a mini ball and want to add unstable-surface work (planks, bridges, squats and balance holds on the dome) it is the premium step up. If you are after a traditional Pilates ball, one of the picks above is the better buy.
