Italian Renaissance interior refers to interior decorations, furnishing and the decorative arts in Italy during the Renaissance period. Massive and regal define the furnishings of the Italian Renaissance interior period. Four-poster beds, trestle tables and storage cabinets were imposing pieces of furniture that often anchored a room. The cassapanca, a twist on the traditional dowry chest, became a place to sit with the addition of a back piece and arms. Different chair styles also appeared, from the sedia, a boxy, throne-like armchair, to the savonarola, a curvy side chair with an X-shaped base. Many furniture pieces were made of rich walnut, which was then intricately carved with architectural details and village scenes. Wall decoration in the Italian Renaissance provided color and texture in the room. Painting the walls with elaborate geometric patterns gave the appearance of wallpaper. Other techniques included trompe l’oeil which added interest with its intricate details and realistic scenes. In addition to wall surfaces, the moldings on door frames, fireplace surrounds and other woodwork were thick and sculptural, adding to the grandeur of Renaissance interiors.
Attention to detail continued on the floors and ceilings of Italian Renaissance interior rooms. Many floors were made of brick, tile or marble laid out in geometric patterns. Ceilings were high and ornamental, with beams frequently stretching across the room. The most decorated spaces featured deep, coffered ceilings, often with detailed carvings or paintings inside each ornamental square.
