Whether you are looking for contrast or complement to today's linear kitchen surfaces, David Lewis' Concave is a curvilinear tour de force. The radical interplay of sweeping angles is a feast for the eyes. Even the smallest details carry through the curved theme. Elica's patented Control Ball is inspired simplicity itself: a touch to the left adjusts the lighting; a touch to the right sets the level of aspiration. A pair of circular stainless steel posts suspends the aluminum wing, done in a cool-blue David Lewis signature hue. And uniform strokes of brushed steel complete the design's dramatic upward sweep.
