The AEO chair was the last product from the Archizoom group, and was designed by Paolo Deganello in 1973 as an unconventional interpretation of a contemporary armchair. Using experimental materials, the piece was originally available for self-assembly. A wide array of upholstery options were on offer, which enhanced the chair’s potential for personalization. The quintessence of functionality and versatility, AEO is thus typical of a Cassina piece, since it can be taken apart and washed, while being light and comfortable, the perfect partner for any space and style.
