Regular seat cushions don't let you strengthen core muscles, exercise your legs, or improve balance and coordination like the FitBall® Seating Disc does.
The 15" diameter inflatable disc has a dome shaped top that mimics the resistant conditions of a regular FitBall®.
You can increase or decrease the inflation to vary the challenge, or use the Seating Disc on the floor for tension relieving stretch exercises.
This air-filled disc has a unique dome-shaped top that mimics the FitBALL® Exercise Ball (sold separately). One of the most versatile fitness and rehabilitation tools available, the FitBALL® Seating Disc can be used as a standard balance disc on the floor or as an Active Sitting cushion that fits in most chairs.
