The base of the Archibald Gran Comfort sits on four steel feet connected by an outer frame with ruthenium finish. The seat structure is made from beech. The backrest structure is steel with perimeter infill consisting of elastic belts, while the shaped upper part is made from deformable rubber. Both structures are finished with scratch-proof black paint.

The seat spring system consists of elastic belts. The seat and backrest padding is composed of two shaped cushions in polyurethane foam, attached to the metal frame using strips of Velcro. The cushions are covered with a goose down quilt, also fixed in place with Velcro strips.

The exterior upholstery of the Archibald Gran Comfort is available here in Pelle Frau^® Safari leather, and the covers can be removed. In the leather version the edge is raw cut and hand-painted in a matching colour.
