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.
