We recognize the shape of objects through our eyesight, whereas the eyesight comes from association functions in a brain. Accordingly, the image of chairs we have known is created by the association functions in a brain based on our memory of chairs that we experienced before, in that sense, the decorative and ornamental parts of the chair for aesthetic purpose may be considered as the outcome of the association functions and are useless and unnecessary in the point of view of functionalism and minimalism, The Grid Chair is the reinterpretation of a well-known classic chair dismantled and reconstructed its original shape with other material. The minimized structure of the chair to sit is only remained from the original and other ornamental parts are erased and removed, leaving the trace. Grid chair was presented in London Design Festival as a selection of young designer’s work in 2009.
