1. A vehicle seat assembly comprising:
- a cushion having an “
A”
surface and a “
B”
surface, a seating portion, and at least one bolster area adjacent the seating portion, the cushion having a plurality of intrusions extending from one of the “
A”
surface or the “
B”
surface towards the other of the “
A”
surface or the “
B”
surface to form a hardness gradient between the at least one bolster area and the seating portion, each of the intrusions having a first dimension extending across the intrusion and a second corresponding dimension extending across the intrusion, the second dimension being spaced further from the one surface than the first dimension and being smaller than the first dimension, the seating portion having a front portion and a rear portion rearward of the front portion, with the front portion having a lower hardness than the rear portion; and
a trim material secured to the seat assembly so a portion of the trim material is disposed over the “
A”
surface of the cushion.
