What tool is used as the base for a casket arrangement?

The base for a casket arrangement is typically made using a floral foam called floral foam or Oasis. This material retains water, providing hydration to the flowers and helping to keep them fresh throughout the duration of the service. It is often shaped to fit the dimensions of the casket and securely holds the stems of the flowers in place. Additionally, some arrangements may use a wire frame or other structural support for added stability.
