"Could a chair do more than just minimize the downsides of sitting? That was the radical idea that Jeff Weber and the late Bill Stumpf had in their design studio. Could they design a chair that actually had positive effects on the body? You can't design without empathy, said Weber, who also designed our Caper chair. Since design has become more technology based, we've had to sit in our chairs in front of computers for longer periods, just like everyone else. We identify with the problems people have as a result of sitting."
