H_O desks have very thick tops and are available in two sizes. The desk top is made of poplar plywood sandwiched between MDF boards, veneered with thick Ash-tinted oak or Louro Preto wood veneer.

The top features longitudinal grout lines, giving the surface a slat-like appearance. The desk mat is made of MDF board lined with saddle leather in dove grey or coffee colour. The metal leg is lined with leather in a colour matching the desk mat and the fronts of the drawer unit.

On the side opposite the leg, the desks feature a Valcamonica porphyry or white porphyry column. The drawer unit can be placed on the right or the left of the user, always on the side of the column; the unit's poplar plywood frame is veneered with Ash-tinted oak or Louro Preto veneer. The drawer fronts are lined with leather. In the standard configuration, the drawer unit has a box drawer and a file drawer. The side of the drawer unit features longitudinal grout lines, giving the surface a slat-like appearance. An opening on the top, near the column, allows the passage of cables. H_O desks can be accessorised with a courtesy panel lined with matching leather.

H_O desks are only available in a light or dark coloured version. In the light version, the whitish-beige colour of the white porphyry column is matched with dove grey saddle leather and the Ash-tinted oak wood tone. In the dark version, the brown-purple tones of the Valcamonica porphyry column is matched with coffee coloured saddle leather and Louro Preto wood tones.

The saddle leather, in both colours, is offered in two surface versions: plain or square pattern, featuring a tone-on-tone motif of 16x16 cm squares obtained through an artisan process.
