Bernt Petersen worked for the famous Danish Mid-century designer Hans Wegner before opening his own studio in 1963. The styles of Wegner can be recognized in his work. Just like Wegner his work for Getama, Bernt used straight lines and beautiful oak wood in his designs. You could think his "Rag" chair to be a piece of work by Wegner himself, if you don't know Petersen.
