Named for the mathematical symbol that resembles an inverted triangle, Nabla bookcase by Melbourne-based VUUE plays with perspective. From the front, the design is deceptively simple, with clean lines warmed by a rich black walnut veneer certified sustainable by the Forest Stewardship Council (FSC). From the side, however, the shelves reveal their true form as inverted triangles. The cabinet base provides hidden storage while working as a counterpoint to the open shelving above. Pair in multiples for a coordinated look.
