What type of casket features sides that are vertical or at right angles to the bottom?

The type of casket that features sides that are vertical or at right angles to the bottom is known as the state casket. State caskets are designed with a more formal and traditional appearance, often characterized by their straight lines and classic proportions. This design is particularly suitable for ceremonial contexts and is frequently used for state funerals or services for dignitaries, where a more formal presentation is desired.

In contrast, elliptic caskets are characterized by rounded sides, while flaring side caskets have sides that angle outward from the bottom to the top. An octagon casket includes an eight-sided design, which does not align with the definition of vertical or right-angled sides. Understanding these distinctions helps in selecting the appropriate casket design based on aesthetic requirements and the context of the service.
