The invention relates to a seat cushion with gradient hardness. Seat assemblies having one or more gradient foam pads are disclosed. The foam pad may have a continuous hardness, density, and/or deflection gradient such that the first end is softer and less density than the second end. The foam cushion may be a single integral foam piece, rather than different layers of foam material assembled together.
