Upper & Lower Adapters for Z4 / YPSI stroller. Allows you to attach Companion Seats, infant car seats, bassinets or any combination.
IMPORTANT: The Z4 / YPSI Double Adaptor allows you to convert your Z4 or YPSI stroller to a combination of stroller with Nido infant seat, or stroller with bassinet or stoller with 2 seats. Nido, Bassinet and Second Seat are sold separately.
This is a great accessory to make the ypsi a double stroller. The only thing I wish were that the instructions were a little better. The bottom adapters were the ones we messed up the first time. Overall very easy to install though
