Which term describes a casket that reveals remaining elements after it has been filled?

The term "Half Couch" refers to a type of casket design where only the upper half of the casket lid can be opened, allowing visibility of the deceased from the waist up while the lower half remains closed. This style reveals elements of the casket's interior, providing a dignified presentation during a viewing. The "Half Couch" option is particularly relevant in understanding traditional funeral practices, where it can be important to balance the display of the deceased with a need for privacy regarding their full appearance.

The other terms have specific meanings that do not align with the description provided. "Open display" typically refers to the practice of displaying not only caskets but also various merchandise openly, while "Partial casket" is not a standard term used in casket terminology and "Full display" usually indicates a casket that is fully open, revealing the entire interior, which contradicts the idea of revealing only remaining elements. Thus, "Half Couch" is the most accurate term that fits the description in the question.
