Multiple foam-filled cells form a cushioned support surface of a seat or mattress. Individual cells may be collapsed by connection through a manifold and valve to a vacuum source. The collapsed cell essentially removes contact pressure in a localized area of the person supported on the surface and restores localized blood flow. After a pre-determined time interval, atmospheric pressure is readmitted to the cell.

The helmet shell of claim 1, wherein said central layer is formed of a soft, pliable, microcellular, viscoelastic foam material, and said inner and outer layers, in their final conditions, take the forms of relatively rigid jackets substantially, and collectively cooperatively, encapsulating the central layer. 3. The helmet shell of claim 2, wherein the surface interfaces between the central layer, and the inner and outer layers are characterized by unitizing mechanical bonds between the layers. 4. The helmet shell of claim 3, wherein said mechanical bonds are structurally characterized by a suffusing of inner and outer layer material with the surface structure of said central layer. 5. The helmet shell of claim 4, wherein said central layer is formed of an acceleration-rate-sensitive material. 6. The helmet shell of claim 5, wherein said acceleration-rate-sensitive material is a microcellular foam material. 7. The helmet shell of claim 1, wherein said central layer is formed of an acceleration-rate-sensitive material. 8. The helmet shell of claim 7, wherein said acceleration-rate-sensitive material is a microcellular foam material.
