The term "coffered" refers to a design feature commonly found in architecture and interior design. It describes a ceiling or surface that is divided into a grid of recessed panels, known as coffers. This technique adds depth and visual interest, often enhancing the overall aesthetic of a room. Coffered ceilings can be made from various materials, including wood, plaster, or metal. They are often seen in grand spaces like palaces, cathedrals, and historic buildings, where they contribute to a sense of elegance and sophistication. The use of coffers can also improve acoustics in larger areas.
