What adapters do I need for multiple children on my &Roll or &Jog frame?Updated a year ago

First, please reference the chart of approved positions to confirm that your desired combination is approved.  Note that the &Roll frame accepts two seats and the &Jog frame accepts one seat.

In general, with the &Roll frame, you would need the Second Seat Adapter Kit, plus an Infant Car Seat Adapter for each of up to two infant car seat models you own.  If you're just planning on using two Switchback Seats, you'll just need one Second Seat Adapter Kit. 

The Bassinet does not require any adapter.
