Abstract
A mattress includes a plurality of air cells. Each cell has a low air permeability envelope and a foam inflation structure that defines one or more voids inside the low air permeability envelope. The foam inflation structures expand when unloaded to cause inflation of the one or more voids. When unloaded, the ratio of the volume of the foam inflation structure to the volume of the one or more voids within the low air permeability envelope is not the same in all the cells.
