One disc per order. Unlike cheaply made discs that are flimsy, hard to pump, and lose air quickly, the King Athletic stability balance disk is easy to fill and holds air longer than other discs, even with continual use and extreme pressure.
Great for hyper children or for kids with ADHD and fidget issues as it helps to absorb their energy and therefore allows them to sit still for longer and stay concentrated better. Our disk works great as a wiggle or wobble seat and is an excellent alternative to a chair balance ball. Strengthen and tighten core and back muscles with stability exercises that target a number of muscle groups.
Made from premium materials, the disc is crafted from high quality, non-toxic and BPA-free rubber composite. Our 13 inch/33 cm diameter disk boost chair comfort with added support and a dual massage surface featuring small bumps and soft spikes.
Please use caution when inflating not to accidentally puncture through the opposite side damaging the disc.
