My child’s head is higher than the vehicle headrest. Is my Clek booster seat (Olli, Ozzi or Oobr in backless mode) still safe to use?
No. The tops of the child’s ears MUST be below the top of the vehicle’s seat back or headrest in the highest adjustment position. If the tops of the child’s ears are above the top of the vehicle seat back or headrest in the highest adjustment position, your child is too large for using the Olli or Ozzi booster seat or Oobr booster seat in backless mode.
