Tacker Stability Bases for Fitness & Balance Balls

A stability or exercise ball that rolls out from under you the moment you pause defeats the purpose. That's where a tacker — a molded stability base or ball stacker — earns its place in a clinic, gym, or home rehab setup. It cradles the ball, keeps it from wandering across the floor between exercises, and turns an unstable ball into a steady platform for seated work, core drills, or supported stretching.

Our current selection features the BodyMed BodySport Fitness Ball Stackers, a set of three interlocking rings designed to hold fitness and exercise balls securely in place. Because they stack, you can raise or lower the ball's resting height and adjust how deeply it sits — useful when you need the ball parked and stable for a transfer, or slightly elevated for a specific movement. The set works with standard fitness balls (the ball itself is sold separately), so you can pair it with whatever diameter fits your program.

Stackers like these matter most for two groups: therapists who need a ball to stay put during controlled, supervised exercise, and anyone using a stability ball as an active chair who wants it to hold position when they stand. They also protect the ball from rolling into equipment and extend its usable life by keeping it off dirty or abrasive floors.

Choosing is straightforward — confirm the stackers accommodate your ball's size, and stack more rings for greater stability or fewer for a lower profile. Because they're lightweight and nest together, they store and transport easily between treatment rooms.

Pair your tacker with the right ball and complementary tools from our Physical Therapy & Rehab collection to build a complete balance and core-training station.
