ABSTRACT OF THE DISCLOSURE An inflatable multi-celled cushion device having a base formed from a fluid impervious material and provided with at least one cavity isolated from the surrounding atmosphere and capable of retaining fluid under pressure. A plurality of cells formed from a fluid impervious flexible material are connected to the base. The cells have hollow interiors isolated from the surrounding atmosphere which open into the base cavity so that the cell interiors communicate through the base cavity. The cells have side walls opposite those of adjacent cells. The cells, when deflated, are generally spaced-apart and have flutes along their side walls, with the flutes of each cell generally parallel and arranged around the entire cell and extending away from the base. The cells are flexible enough that, when pressurized, they will expand laterally so that the flutes are generally obliterated and the side walls of adjacent cells are in contact for substantial portions of their length so as to interfere with each other. The cells are such that, when pressurized further, their ends present a generally continuous outwardly facing surface which will con- form to the shapes of objects brought against it.
