What kind of adapter would allow me to use Triv carrycot from UK work with Triv Next stroller in the US? And where do I find the adapter?
This is a question for the Nuna customer service more than me. They made it purposely so that there is a new frame, new carrycot, and only Nuna car seat compatibility, and since I personally don't have both these models at hand, I cannot tell you whether they are really compatible. The Nuna adapters' availability is an even more complicated matter. I recommend writing to Nuna directly.
