Gustavian style evolved with clear national features. The style is rooted in an interest in antiquity and the excavations at Pompeii and Herculaneum. The elegance and high quality are retained from the Rococo period, but instead of the soft flowing lines and asymmetrical shapes, symmetry, straight lines and simplicity prevail. The curved lines of the Rococo bureau were straightened, and the furniture was endowed with colorful intarsia, gilded borders and trim. The chairs were painted, preferably in gray or gray-green, chair legs were straightened and backrests became square or oval.
