Achille Castiglioni and Giancarlo Pozzi worked together on two designs in the early 1990s; the Trio shelf and Comodo storage unit. Both were testaments to Castiglioni's preoccupation with maximising space and minimising components.
Danish brand Karakter acquired the rights to several pieces designed by Castiglioni ahead of the centenary of his birth in 2018, including the two pieces designed in collaboration with Pozzi.
