The designer Paolo Lomazzi was born in Milan in 1936 and studied at the city's Polytechnic where he met Gionatan De Pas and Donato D'Urbino. In 1969 the trio founded the design office DDL, which remains famous for the inflatable chair Blow for Zanotta, one of several unconventional seating designs by DDL.
For Zanotta, Lomazzi, De Pas, and D'Urbino also designed the wardrobe Sciangai, reminiscent of the game Mikados. In addition, the trio cooperated with manufacturers such as Alessi, Artemide or Cassina. Following Gionatan De Pas's death in 1991, the trio has been a duo: the legacy of the trio and their contribution to pop culture and furniture design history remains intact.
