A vehicle seat assembly is provided having a seat bottom and a seat back assembly connected to the seat bottom. The seat back assembly includes a support frame having a pair of opposing substantially vertical side frame members which receive an elastomeric support webbing. The elastomeric support webbing extends between and cooperates with the opposing side frame members to provide structural support for the passenger seated in the vehicle seat. Side bolsters are attached to the elastomeric support webbing adjacent the opposing side frame members. A headrest or upper bolster is secured to the top of the seat frame adjacent the side bolsters.
