Danish furniture brand Fritz Hansen has commissioned seven architects including Zaha Hadid, Jean Nouvel and Snøhetta to reimagine the Series 7 chair by Danish Modernist Arne Jacobsen, to celebrate the iconic product’s 60th anniversary. BIG, Carlos Ott and Carlos Ponce de León, Jean Nouvel Design, Jun Igarashi, Neri & Hu, Snøhetta and Zaha Hadid Design all answered the call from Fritz Hansen to create versions of Jacobsen’s original 1955 plywood chair. Formed from two continuous steel rods, the sculptural base of Zaha Hadid’s bright green design was influenced by the organic and fluid forms that typify her buildings.
