A seat assembly includes a seat member having a support surface, wherein the support surface is disposed at an inclined angle from a rear portion to a front portion thereof. A seat cover covers the support surface. An airbag assembly is disposed below the seat cover at the front portion of the support surface at a thigh support region. The airbag is operable between inflated and deflated conditions, wherein the airbag assembly increases the inclined angle of the support surface when the airbag assembly is in the inflated condition.
