A completely integrated metallic seat pan with a negative stiffness includes a seat pan base, an internal metallic lattice, and a metallic seat pan cover surrounding the metallic lattice. The metallic lattice and seat pan cover elastically deform to absorb the weight of the crewmember and provide cushioning. The seat pan cover is contoured. Portions of the contoured seat pan cover may have greater or lesser cross-sectional thickness to provide variable negative stiffness at different locations on the seat pan.
