Gustavian style is a design movement that emerged in Sweden during the late 18th century, particularly under the reign of King Gustav III. It is characterized by its elegant simplicity, light colors, and neoclassical influences, often incorporating elements from French and Italian styles. Furniture and interiors in Gustavian style typically feature clean lines, delicate carvings, and a palette of soft pastels, such as pale blue, gray, and white. This style reflects a sense of refinement and tranquility, making it popular in both residential and public spaces during the period.
