Modern design started around World War I and generally featured flat surfaces, geometric forms, and little or no ornamentation or adornments. Modern kitchen cabinets, for example, are often defined by a sleek, angular and simple design, featuring little or no hardware, flush doors and flat surfaces. In the current era, modern kitchen design is part of a larger trend which has embraced midcentury modern design and furniture, which introduced bold angles and curves to the design landscape. Midcentury modern design—generally recognized as originating in the Nordic countries in the mid 20th century—has now been incorporated into many modern kitchen designs.
