Use this double adapter set to attach a Companion Seat to your Agio Z4 stroller or Peg-Perego YPSI stroller.

This set includes the upper and lower adapters needed to create space between the main stroller seat and lower Companion Seat. If attaching two Agio or Peg-Perego Primo Viaggio series infant car seats for twins, you will also need to purchase an additional set of Primo Viaggio links for the second car seat.
