The Loop de Loop line of chairs is an original design by William Pedersen Designs. Many thought this project would be impossible to achieve, but by using an algorithmic process, it was able to come to fruition. This project encompasses the ability take a free from design, rationalize it with fabrication constraints and use the 3D model to drive the fabrication equipment. The free form geometry is derived from specific proportions which relate to the proportions of the human body and its posture for comfort while seated. Conceptually, the elegant gesture is a simple closed loop that rolls on itself. The geometry of the loop continuously changes direction and curvature in 3D space, this is a challenge when trying to fabricate the piece. Various technologies are looked at and none can create this level of varying curvature. One of the final technologies that has the most promise is a CNC bending machine that is used to create spring components. After talking to the makers of the CNC equipment and understanding the different bending technologies and their constraints, these were fed back into the 3D model and with tight tolerances, the geometry is form fitted to maintain the overall proportions of the chair while allowing it to be constructed. The new-found geometry is then converted into machine code to drive the CNC bending equipment. This project has as special meaning in my career, where design and fabrication blended seamlessly, and the ability to work directly with Bill Pedersen himself.

The Loop de Loop line of chairs have been displayed and talked about in a number of publications and events including the International Contemporary Furniture Fair for several years in a row, the New York Times (May 21, 2014), the National Academy Museum, Architectural Record (September 2012, May 2014), Architect magazine (May 23, 2014), the Architectural Record’s Innovation Conference (October 2012), and the McNeel news site (July 2015)
