This design for a modular casket uses a tension cable system to function as the weight bearing floor for the interior. The cable weaves through eyepieces mounted to either stanchions or side panels to form a zigzag webbing along the bottom of the casket and tension is applied to the cable using a ratchet. The interior flooring is completed by laying a sheet of foam over the cable webbing on top of which the casket's mattress is laid. Both the lid and the base are comprised of four partitions that are either flexibly attached to one another to enable a compact accordion like fold or are separate pieces which easily align. In both the wood and steel versions of this design, the caskets are fully assembled without the use of tools.
