The chair is inspired by the „Rollassel“, an insect that can switch its body into a ball.
A sphere is the most stable and at the same time, related to a surface, the most labile body. By changing the shape, to get stability in relation to the surface, the form changes from stable to
labile. The closed seat creates an octagon, such as the insect.
The design of the three outer shells and their cushion elements are depending on their functional relationship.
