Nettek is a generative chair design. It emerged from a collaboration with Hannes Zweifel Architektur. It was submitted to the 2009Design Award SWB @ Embru. In the tradition of Embru, the chair is entirely made of metal. It consists of a frame and chain mail seating.
The frame is a rod of steel bent into the desired shape. Both ends are welded to each other. The multiple torsions increase the stability of the frame. The chain mail adapts to the body and thus creates a soft and pleasant form to sit on.
Sketches and small wireframe models where first used to explore different shapes. Later, a computer-generated, parametric model was developed. A combination of Rhinoceros and Grasshopper were mainly used for that. Additionally, VB .NET components where used for creating a chain cloth simulation. The parametric model helped to find the appropriate curves, slopes, and ultimately find the ideal shape. The numbers of chain links used for the seat automatically adapted to the form of the frame. Despite the indispensable use of the computer model, the product should not celebrate this, but reflect its simple and natural form inspired by traditional handicraft. The chair is bound to both tradition and new process technologies which results in a familiar-looking shape while expressing something contemporary.
