Designed by Claudio Silvestrin, the H_O desks have very thick tops and are available in two different sizes. The surfaces are made of poplar plywood sandwiched between MDF boards and are veneered with thick-cut Ash-tinted oak or Louro Preto.
The upper part of the surface features a number of joints that show the craftsmanship of the horizontal slats. The desk pad, made from an MDF panel, is always covered in Cuoio Saddle leather in the colours Tortora or Caffè. The leg is made of metal and upholstered in saddle-leather that matches the desk pad and the fronts of the drawer unit. On the opposite side to the leg, the H_O Desk has a column in Valcamonica porphyry or White porphyry. The H_O President Desk and H_O Executive Desk come in both light and dark versions. The light version sees the White porphyry column, with its white-beige colours, paired with Tortora saddle-leather and the tones of Ash-tinted oak. In the dark version the column in Valcamonica porphyry, with its browny-red tones, is matched with Caffè saddle-leather and the tones of Louro Preto wood. The H_O desks can be accessorised with a modesty panel covered in matching saddle-leather. The saddle-leather, in the two colours, can be either plain or feature a 'square' pattern which is handcrafted to produce a tone-on-tone motif with 16x16 cm chequers.
The H_O drawer unit, which can be positioned to the right or left of the user, but always on the same side as the column, has a poplar plywood structure with Louro Preto or Ash-tinted oak veneer and front in saddle-leather. The drawer unit consists of a drawer and a filing drawer or compartment with door. The joints on the side of the drawer unit show the craftsmanship of the horizontal slats. On the surface, near the column there is an opening through which electric cables can be passed.
