A certain design movement that arose in the early to mid-20th century—more specifically, from the 1920s to the 1950s—is the source of modern home décor. It places a strong emphasis on utility, simplicity, and absence of decoration. Clean lines, subdued colour schemes, and the utilisation of organic materials like metal, leather, and wood are important components. With an emphasis on open spaces and minimalism, furniture in modern décor is frequently low to the ground. The aesthetic disapproves of excess and adopts the “form follows function” theory, according to which each component of design has a functional use.
