Armchair, 2000

This armchair is generated from a grid of 4×6 squares formed by black wooden strips with a square cross section of 3.5×3.5 centimeters. The square openings have twice the width of the wooden strips. Only the tilted and radially rounded seat back breaks out of this logic. It is a concession to the comfort of sitting: by breaking the logic, it offers the targeted severity of an antipole. For the chair, several prototypes were created: they were no longer just an aesthetic formulation, but instead the subordinate development of an ergonomic seating position accordin to Kleihues. His geometrical clarity dominated this chair.
