"Stool (no. 4)" by Ai Weiwei is a painted wooden work that references traditional Chinese furniture design while engaging with themes of cultural transformation and contemporary art practice. Created by the renowned Chinese artist and activist, the work exemplifies how Weiwei subverts everyday objects to create conceptual statements about heritage, mass production, and artistic intervention. The painted surface and serialized numbering suggest both industrial processes and the artist's broader interest in decontextualizing functional objects as sculptural and political statements.
