Chaise n°4 is a minimal chair created by Paris-based studio L’Établissement. L’Établissement’s Chaise n°4 embodies a disciplined approach to furniture design, blending artisanal craftsmanship with a minimal, architectural form. Constructed from stained and lacquered oak, this chair reflects the atelier’s commitment to refined materiality and precise fabrication. The design plays with linearity and volume, using intersecting planes to create a striking, sculptural silhouette. A curved backrest provides visual balance to the otherwise rigid geometry, offering a subtle nod to comfort while maintaining the chair’s structural clarity. The seat, slightly softened at the edges, contrasts with the bold, vertical supports, reinforcing a sense of thoughtful equilibrium. L’Établissement’s meticulous attention to detail is evident in the way components connect — joints are deliberate, visible, and honest. The rich, dark stain enhances the wood’s natural grain, emphasizing the material’s texture beneath the glossy finish.
