After fifty years, what is there left to write about one of the icons of Italian design that, still today, communicates the absolute strength of ideas – that is, when such strength really exists? Nowhere, in the written history of design, is this object not positioned among the top ten icons that changed the perspective of our beloved field forever and for everyone.

Perhaps we can add that – beyond the desecrating gesture of filling a sack (Sacco) with polystyrene balls in order to transform it into the most informal, most versatile, most irreverent, most freeing, most soft, most ergonomic and ‘most’ everything chair – there is no defined shape. It is for this very reason that it has survived, untouched by time, through seasons, fashions and every ‘ism’ imaginable, preserving the greatest value of all: being a concept that well beyond the seasons, arriving undamaged to the present day, is ready to be adapted into versions for children and teenagers, because to encourage smiles and fun even while sitting in an ‘armchair’ is not a luxury reserved for adults.

The idea of its designers was to realize a “universal” seat that would easily adapt to any body, in any position. Sacco is no doubt one of the most brilliant objects that have marked the Italian Design.
