A padding body (10) that has a flexible grid member (54) with apertures (76) formed in it. The apertures a e defined by bordering sections (80) of the grid member. The padding body includes individual modular elements (24) with each modular element being resilient and each modular element having an intermediate section (38) and an upper protuberance (34) extending upwardly off from the intermediate section. The individual modular elements have a peripheral slit or recess (44) 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 (12) formed entirely of foam material. The frame structure includes foam blocks (14) 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. The height of the individual modular elements is preferably of the same elevation as the stacked foam blocks such that the grid is suspended between the border blocks either in a non-web state or during use. A plurality of transverse columns (185, 187, 189, 191, 193) of modular elements positioned longitudinally intermediate of the transverse columns is formed of a firmer polyurethane foam to provide better support in those areas of a body which need added support.
