Abstract:
1. A cellular cushion comprising: a base comprising at least a first layer, a second layer, and an axis of symmetry extending therethrough, each of said first layer and said second layer comprise a substantially planar lower surface and a substantially planar upper surface that is opposite said lower surface; and a plurality of hollow cells coupled to said base and extending outwardly from said first layer upper surface within at least one region, each of said plurality of cells within each said region are coupled together in flow communication, each of said plurality of cells comprises a hollow body portion and an outer surface, said plurality of cells are spaced across said base such that said plurality of cell outer surfaces cooperate to define a contoured seat configured to cradle a user's buttocks, said plurality of cells comprising a plurality of first cells and a plurality of second cells, at least some of said plurality of first cells and said plurality of second cells have a substantially circular cross-sectional profile, an outer surface of each of said plurality of first cells is substantially parallel to said base, an outer surface of each of said plurality of second cells is oriented obliquely with respect to said base, at least some of said plurality of second cell outer surfaces are sloped towards said centerline axis of symmetry, at least some of said plurality of second cell outer surfaces are sloped away from said centerline axis of symmetry.
