One of Denmark's most prolific designers of mid-century modern furniture, Kristiansen designed a broad range of chairs, sideboards, desks, tables and shelving units starting in the early 50's. But the most widely recognized of all his designs is undoubtedly his No.42 Dining Chair, now produced exclusively in Shikoku, Japan. Now in his 80s, Kristiansen still visits the workshop every year to oversee production.
