The aesthetic and conceptual motif for Quatro is four-leaf. Its mildly concaved surface displayed a structural potential to be a seat top while its cultural context had an innocent and melancholic appeal that is conceptually conducive to the piece.
Quatro is designed to fit in both commercial and private settings. Powder-coated aluminum base requires low maintenance while providing high resilience to the abuse in communal settings. The four curvatures inside Quatro are an index for users to effortlessly grab and move the stool.
