The Doppler sideboards supplement the Doppler coffee table collection designed by Giuseppe Viganò for Bonaldo. They propose the same illusion of overlapping surfaces, whereas actually the doors are made up of a single surface: indeed, it is the combination of various brightly coloured graphic patterns that creates this particular optical effect. The asymmetrical opening of the doors is an additional sign of originality. The lacquered wood frame is supported by a solid ash-wood base, painted in grey or walnut-wood. Bonaldo produces the Doppler sideboards in two different sizes: one high and the other low, to furnish both the living room and the bedroom.
