Radian Chair / Chair

Radian Chair
Radian Chair

The concept is to design a chair that appears structurally strong and hard but it is actually flexible. The rectilinear "rib-like" steel frame creates a strong and rigid appearance visually. By carefully placing the individual freestanding bar radially - the bigger the angle the more flexible it is, it would bend to accommodate a user’s body weight. When a user sits on the chair, the more perpendicular bars will create more support, and the more diagonal bars will be more flexible and bouncier. Thus the chair is more comfortable to sit on than it appears.
