Which feature is essential for the functionality of casket handles?

The functionality of casket handles primarily revolves around mobility, making it crucial for their design. Casket handles are intended to facilitate the lifting and transportation of the casket during ceremonies and burials. They need to be sturdy and well-placed, allowing pallbearers to securely grip and maneuver the casket, which often requires lifting it with precision and care.

While accessibility is important to ensure that handles can be easily reached, it doesn't directly affect the primary function of the handles themselves. Deco design plays a role in the aesthetic appeal of the casket but does not contribute to the functional aspect of how handles allow for movement. Cost-effectiveness is more related to the overall pricing and budgeting for funeral services rather than the practical use of the handles. Hence, mobility stands out as the core feature necessary for the effective functionality of casket handles.
