The Stainless Steel Stool 400, designed by Jeongwha Seo for Dior in 2022, is a rigorously composed object defined by geometric clarity and carefully measured proportions, balancing function with sculptural presence. Constructed entirely from stainless steel, it emphasizes material continuity and structural legibility, allowing surface, weight, and light to articulate the form without ornament. The design reflects Seo’s commitment to reduction and precision, presenting the stool as an exercise in essential form and quiet material authority.
