A seat assembly includes a seat bottom with a deformable seat shell. The deformable seat shell is configured to change shape with a changing occupant load distribution. The seat shell is coupled with a support frame via a shell motion controller having one or more motion control links. Each motion control link is coupled with the seat shell at a fixed location relative to the seat shell and with the support frame at a fixed location relative to the support frame. The shell motion controller allows these fixed locations to move relative to each other and also constrains their relative movement. The combined seat shell deformation and controlled movement relative to the support frame can provide the seat occupant with a comfortable seating experience while preventing pelvis drift and potentially eliminating traditional foam seat cushions.
