Excuse the background noise, wanted to show my girlfriend how I use them both together and for anyone else wondering about the attachment! Amazon registry gives you 15% off the UppaBaby Vista stroller, and we purchased the Nuna during Nordstrom's annual sale. I like how light the Nuna is, the supportive base, and various inserts as the baby grows. UppaBaby was my favorite for a double stroller so that's why we went with that over the Nuna stroller!
