Do you know how much your work efficiency decreases when you work while sitting? If you sit for long periods of time, your concentration will decrease as you become tired. Movies are usually two hours long, or at most three hours long, but this is the limit of the amount of time a human can concentrate while sitting. If you keep working, your concentration will drop to the point where you won't even notice that your efficiency is decreasing. Therefore, we developed a chair cushion that helps you correct your posture. Continue sitting on the balance ball to maintain correct posture. This cushion is not a product that you can feel the comfort of sitting on it the moment you sit on it, but it is only after sitting for a long period of time that you will notice that it is less tiring. Comes with a start guide to help you understand how to use it correctly. *This cushion changes the way you sit only when you are using it, and does not change the way you sit when the cushion is not in use.
