Hi Napper and Ari,
While mattress companies do often change foam sources and often consider that information proprietary, or the consumer it’s nice to at a minimum know if the foam is domestic or not. And if sourcing might change from one country to another, it’s quite simple to update that on a web site 
. From what I can find, the foam still seems to be sourced from China, which can bring up these concerns.
I’m sorry your Nectar didn’t work out for you 
. Rebranding is indeed a common occurrence in the online mattress community.
