When designing the Fidelio series (Low Cabinet, High Cabinet and Mobile Bar), Roberto Lazzeroni opted for a deliberately clean design combined with precious materials: formal simplicity and sophisticated finishes for a versatile collection that is easy to combine with all other Poltrona Frau furnishings. The functional details become highly distinctive aesthetic elements, like the recessed handles on the surfaces. There is also the intense contrast between the warm, dark tones of the saddle-leather and wood that covers the exteriors, and the luminous explosion of the light natural maple that reveals itself in the compartments. The collection includes the Low Cabinet, the High Cabinet and the Fidelio Mobile Bar. The supporting structure is in solid ash and birch plywood with moka-coloured ash veneer on the outside. The extra light natural maple wood brightens the interior. The doors are in birch plywood and poplar with the insides veneered in moka-stained ash for the Fidelio Low Cabinet and extra light natural cut maple wood in the Fidelio High Cabinet. The edging of the doors is produced from solid ash in a moka stain. The top is available in moka-stained ash, in glossy or semi-glossy Calacatta gold marble and in glossy Emperador marble. The sawhorse base, in moka-stained solid ash with triangular cross-section, adds to the light feel of the design. The base is fixed to the structure with cylindrical spacers in matt black painted steel. The adjustable steel feet have rubber caps. Fine saddle-leather is used to upholster the sides, doors, inside drawers and, on request, the back of the cabinet. Choice between tone-on-tone or contrast stitching. The inside of the Fidelio Mobile Bar is designed to lighten up when the doors are opened. The back wall of the cabinet is covered with two bronzed mirrors.
