Which material is commonly used for cushioning in casket interiors?

Excelsior is a traditional material commonly used for cushioning in casket interiors due to its lightweight nature and ability to provide a soft, protective layer. This material is typically made from shredded wood and is designed to absorb shocks, protecting the items within the casket while also offering a degree of comfort. Its historical use in funerary practices and the natural, biodegradable properties make excelsior a suitable choice for funeral homes seeking to provide a classic and respectful presentation.

In contrast, EVA foam is primarily used in sports and footwear for its lightweight and shock-absorbing qualities but is not traditionally associated with casket interiors. Memory foam, while known for its comfort and support, is more commonly found in modern bedding and furniture rather than in casket design. Fiberglass, on the other hand, is a synthetic material used for structural purposes and does not provide the cushioning effects required for casket interiors. Thus, excelsior remains the preferred option for its blend of tradition, cushioning ability, and environmental considerations.
