Named for the mathematical symbol that resembles an inverted triangle, Nabla bookshelf 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. Pair in multiples for a coordinated look. CB2 exclusive.
