1. A method of making a vehicle seat assembly, the method comprising:
- providing a cushion having an “
A”
surface, a “
B”
surface, a seating portion, and at least one bolster area adjacent the seating portion, the seating portion having a plurality of intrusions extending from the 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 of between 8% to 25%, 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;
securing the cushion to a frame; and
securing a trim material to the seat assembly so a portion of the trim material is disposed over the “
A”
surface of the cushion.

11. A method of making a vehicle seat assembly, the method comprising:
-
providing a cushion having an “
A”
surface, a “
B”
surface, a seating portion, two side bolster areas laterally spaced from each other and adjacent the seating portion, and a front bolster area extending in front of the seating portion and between the side bolster areas, wherein each of the side bolster areas have an uppermost surface portion elevated relative to an uppermost surface portion of the seating portion to enable the bolster areas to be capable of supporting an increased load relative to the seating portion, the seating portion of the cushion having a first 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 at least one of the side bolster areas and the seating portion of between 8% to 25%, and the front bolster area has a second plurality of intrusions, less than the first 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 front bolster area and the seating portion of 5% to 20%, wherein the side bolster areas do not have any pronounced holes formed therein, 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;securing the cushion to a frame; and covering the cushion with a trim member. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method of making a vehicle seat assembly, the method comprising:
-
providing a cushion having an “
A”
surface which would be adjacent to an occupant if an occupant was seated in the seat assembly, a “
B”
surface, a seating portion, and at least one side bolster area laterally adjacent the seating portion, wherein the at least one side bolster area has an uppermost surface portion elevated relative to an uppermost surface portion of the seating portion, the seating portion of the cushion has a first 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 side bolster area and the seating portion of between 8% to 25%, wherein the at least one side bolster area does not have any holes formed therein, 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;securing the cushion to a frame; and covering the cushion with a trim member. - View Dependent Claims (20)
