X CHAIR is a minimalist chair designed by Seoul-based artist Lee Sisan. Crafted from standardized industrial square pipes—a material predominantly utilized in architectural constructs—this series by designer Lee showcases an intriguing approach to furniture and object design. By adopting a straightforward method of assembly, where pipes of varying dimensions are either connected or intersected, Lee accentuates the inherent structural qualities of these materials. The collection stands as a testament to embracing the unintended, where the natural outcomes of the manufacturing process are not only accepted but celebrated as integral elements of the design. Lee’s work draws particular attention to phenomena often regarded as manufacturing defects. For example, the process of welding stainless steel induces heat scorching, resulting in a spectrum of hues on the metal’s surface, varying according to the temperature applied.

Similarly, aluminum’s susceptibility to scratches is intentionally leveraged to create a distinct finish, underscoring the material’s natural tendencies. Typically, such marks would be deemed imperfections, detracting from the product’s market value and aesthetic appeal. In stark contrast, Lee’s exhibition boldly showcases these “flaws,” integrating them into the design narrative. The deliberate preservation of these traces on the steel’s surface transcends mere aesthetic appreciation, bridging the gap between design and art. These marks are not only visual records of the material’s journey but also serve as a reflection of the designer’s contemplative process, navigating the fine line between artistic expression and functional design.
