A method is provided with a stranded mesh material blank inserted into a cavity of a tool assembly shaped to form a cushion member. Fluid is circulated above a first temperature threshold through a series of apertures defined in a forming surface of the tool assembly and into the cavity thereby softening the blank and conforming a shape of the blank to the forming surface. Fluid is circulated below a second temperature threshold through the series of apertures in the forming surface and into the cavity thereby setting the shape of the blank to the forming surface and forming a cushion member. A cushion for a seat assembly is provided by a stranded mesh material member. A system is provided with a first tool, a second tool, and one or more inlet manifolds.
