Limited materials and processing methods sometimes stimulate a designer's imagination. One sereis uses a single sheet of metal without waste and at the same time creates new formative and functional relationships as art furniture through minimal processing. One bench conveys visual balance and tension by having identical curved shapes intersecting each other. Functionally, it is in the form of a bench on which a person can sit, and is designed to provide a different sense of balance depending on where one sits. The lower part of the bench, naturally formed by the structure, exists as a functional space where objects can be placed. One shelves sought to find another story about an object through a vertical interpretation of the same concept. As shapes intersect, the roles of objects are naturally defined. One side becomes an open shelf, and the other side creates a closed space on three sides. Accordingly, we wanted to show people various experiences of dealing with objects. In One Table, we attempted to expand the concept of the series through repetition of shapes. The rotating, repeated structure not only allows the table to be stably balanced, but also stimulates people's curiosity by creating a contrast between the static image seen from above and the dynamic curves below.
