What is the purpose of coffers in ceiling design?

Coffers in ceiling design serve primarily to create geometric decorative patterns that enhance the visual interest of a space. This technique is often used in various architectural styles, providing an aesthetic appeal through the repetition of shapes. The use of coffers can add depth and complexity to flat ceilings, creating a sense of rhythm and inviting light and shadow play that enriches the overall ambiance of the interior.

While coffers may incidentally reduce the weight of the ceiling due to the removal of material, their main intention is decorative rather than structural or functional in nature. They do not typically serve the purpose of providing ventilation or adding structural support like beams would. The emphasis is on the artistic arrangement and visual impact, making them a favored element in classical and neoclassical architectures, among others.
