Three factors can even be taken to reveal that there is a greater need for dynamic chairs in meetings and conferences than in a normal, personal office.
1. In a meeting, you probably have much less space in which to vary the position of your body than you do in your normal workplace. 2. In a meeting, you probably have to sit in the same position for a longer period of time than you would in your normal workplace. 3. In meetings/conferences, you have to be better behaved than you do in your normal workplace.
A universal chair that fits anywhere people are supposed to sit.
