Abstract: A cellular cushion includes a base, a plurality of hollow cells, and a sealing layer. The base includes at least a first layer and a second layer. The plurality of hollow cells are coupled to the base and extend outwardly from the base. Moreover, the plurality of cells are coupled together in flow communication. The sealing layer is coupled to at least one of the base first and second layers. At least one of the sealing layer and the base defines a plurality of lock pockets, wherein each of the lock pockets is positioned between adjacent hollow cells for selectively controlling flow communication independently to each of the plurality of hollow cells within the cellular cushion.

Abstract: A cellular cushion includes a base and a plurality of hollow cells. The base includes at least a first layer and a second layer. The hollow cells are coupled to the base and extend outwardly from the base within at least one region. Each of the cells within each region are coupled together in flow communication. Each of the cells includes a hollow body portion and an outer surface. The plurality of cells are spaced across the base such that the cell outer surfaces define a contoured seat configured to cradle a user's buttocks. The cells also include a plurality of first cells and a plurality of second cells. An outer surface of each of the first cells is substantially parallel to the base. An outer surface of each of the second cells is oriented obliquely with respect to the base. At least some of the cells are substantially cylindrical.
