Abstract: A padding body that has flexible grid member with apertures formed in it. The apertures are defined by bordering sections of the grid member. The padding body includes individual modular elements with each modular element being resilient and each modular element having an intermediate section and an upper protuberance extending upwardly off from the intermediate section. The individual modular elements have a peripheral slit or recess formed in the intermediate section. Each of the individual modular elements are releasably fixed within a respective one of the apertures formed in the grid. One embodiment of the padding body includes a frame structure formed entirely of foam material. The frame structure includes foam blocks stacked two high. Apertures and the bordering sections of the grid member spaced about the periphery of the grid member are secured between the upper and lower stacked foam blocks so as to suspend the grid member.
