  • 4 LAYER SIDE IMPACT PROTECTION - Extra deep aluminum reinforced sides provides 4 layers of enhanced side impact protection for their head, shoulders and torso.
  • EXPANDABLE HEIGHT & WIDTH - 11 headrest positions and expandable side walls provides 69% increase in occupancy space as your child grows.
  • TWO SEATS IN ONE - Easily converts from a high back booster to a backless booster seat with wide contoured seat base and two retractable cup holders.
