Aksel Bender Madsen was trained as a cabinetmaker. He attended the Furniture School at the Royal Danish Academy of Fine Arts, graduating in 1940. He worked with architects Kaare Klint and Arne Jacobsen until 1943. Starting 1942 he designed his own models which he exhibited at the annual Cabinetmakers Guild's exhibitions in Copenhagen. While studying at the Academy, he met Ejner Larsen who became his partner. In 1947, they established a design studio together. The same year, they presented works made by cabinetmaker Willy Beck at the Cabinetmakers Guild's exhibition in Copenhagen where they continued to participate year after year, working with Beck for a total of 25 years. In addition to sculptural chair designs, they also designed living rooms, bedrooms, shelving, dining tables, and office furniture. Their most notable work is the famous Metropolitan Chair, in bent plywood, which was exhibited in 1949 and manufactured by Fritz Hansen from 1952. All their works have a clear, timeless, simple style which continues to please today. In Madsen's own words: "What Ejner Larsen and I have made has always been in line with the principles we learnt from Kaare Klint about what is functional and what is natural. The requirements made set the design." Madsen also taught at the Danish Design School in Copenhagen from 1946-1954.
