Original MGAD design (Macchione & Guga ArchDesign), Frege Stool is composed of a finely researched Plexyglass structure. In addition to the icy design and the coldness of the Plexyglass, the Stool stands out for the possibility of extreme customization that MGAD offers, i.e. with the easy replacement by means of hand screws, of the seat (TOP) which in the appropriate catalog can be chosen among the current 35 collections and 182 different colours.
