The modern, innovative style known in Sweden as functionalism was introduced at the 1930 Stockholm Exhibition. The international name for this style is modernism, or the International Style. The style is characterized by simple geometric shapes, lack of embellishment, clean surfaces and the idea of placing the function of the object at the center. Form and function are considered to be interdependent. An easily-cleaned home is valued, which influences the interior design. Furniture was made of tubular steel and bentwood. Black was the height of fashion.
