The Slim Seat is slightly unstable because its chamber of air moves when you sit on it - it’s like sitting on an exercise ball. To keep balanced, you unconsciously, or automatically engage your abs and core to stay upright. It’s ab-active sitting. You’re sitting, but your abs are working to stabilize your core. Even if you cannot see any movement, your abs are still making tiny adjustments to keep you balanced. You won’t even know you are getting fit.

Studies have shown that sitting on an exercise ball helps kids learn better and makes workers more productive, but not everyone can sit on a ball at work. Now you can get the same effect just by putting the Slim Seat cushion on your chair. For the first time, you can work your abs and core when you sit, which is doing what you do every day at work or at home. Just like the new sneakers that give you a workout with every step, now you can get a workout with every minute you sit.
