He introduced the style of lacquered art deco furniture in the late 1920s, and in the late 1930s introduced furniture made of metal with panels of smoked glass. In Italy, the designer Gio Ponti was famous for his streamlined designs. The costly and exotic furniture of Ruhlmann and other traditionalists infuriated modernists, including the architect Le Corbusier, causing him to write a famous series of articles denouncing the arts décoratif style. He attacked furniture made only for the rich, and called upon designers to create furniture made with inexpensive materials and modern style, which ordinary people could afford. He designed his own chairs, created to be inexpensive and mass-produced. In the 1930s, furniture designs adapted to the form, with smoother surfaces and curved forms. The masters of the late style included Donald Deskey, who was one of the most influential designers; he created the interior of the Radio City Music Hall. He used a mixture of traditional and very modern materials, including aluminium, chrome, and bakelite, an early form of plastic. Other masters of art deco furniture of the 1930s in the United States included Gilbert Rohde, Warren McArthur, Kem Weber, and Wolfgang Hoffman.

It was influenced by modern aerodynamic principles developed for aviation and ballistics to reduce aerodynamic drag at high velocities. The bullet shapes were applied by designers to cars, trains, ships, and even objects not intended to move, such as refrigerators, gas pumps, and buildings. One of the first production vehicles in this style was the Chrysler Airflow of 1933. It was unsuccessful commercially, but the beauty and functionality of its design set a precedent; meant modernity. It continued to be used in car design well after World War II. New industrial materials began to influence the design of cars and household objects. These included aluminium, chrome, and bakelite, an early form of plastic. Bakelite could be easily moulded into different forms, and soon was used in telephones, radios and other appliances. Ocean liners also adopted a style of Art Deco, known in French
