The Agio Z4 and Peg-Perego YPSI strollers are compatible with all five versions of the Nuna PIPA series infant car seats, using these adapters.

Since you have several models to choose from with the Nuna PIPA series, you might be wondering what the differences are and which may work best for your needs. This video compares the Nuna PIPA, PIPA RX, PIPA Lite, PIPA Lite R, and PIPA Lite LX:

How to use your Nuna PIPA car seat on the Agio Z4 or Peg-Perego YPSI

To attach your Nuna PIPA series Infant Car Seat to the Agio Z4 or Peg-Perego YPSI, you will need to purchase these Agio Z4 car seat adapters, sold separately from the stroller. These adapters are a set of two small posts with a glossy button at the front of each used to detach the adapter from the stroller. If using your Z4 or YPSI stroller as a double for twins, you will need to purchase two of these adapters, as well as the Z4 / YPSI Double Adapters, to attach two PIPA car seats at once.

Please note these adapters will not fit a Stokke PIPA, which is a car seat made by Nuna for Stokke strollers exclusively.

To attach the car seat to your stroller, remove the stroller seat and place the adapters on either side, with the glossy button facing forward. Then lower the PIPA infant car seat onto the adapters so baby is facing the handle of the stroller, until you hear the adapters click into place.

To remove the car seat from the stroller, you will press the small grey buttons on either side of the PIPA car seat, located on the car seat near where the car seat handle rotates. While pressing down on these buttons, lift up on the car seat to remove from the stroller! You may find it easier to release one side of the car seat at a time while lifting up on the car seat handle. The adapters can stay on the stroller, but should be removed before attaching a bassinet or the stroller seat; just press the glossy buttons on each adapter and lift up to remove from the frame.
