I seem to remember when we bought our bed from King Koil / Simmons they had feather pillows and duvets made from Canadian down. We bought our bed at the one on Junin -- I think it is around Independencia that you find a whole bunch of bedding / mattress stores in a row. However there are Simmons places around town now. Also I think Rosen is supposed to be good quality. Sorry I can't help too much -- I brought mine down from Canada ages ago, will probably replace it when I'm back there this year! Try a search on the forum for the mattress store location though and you should have some luck along that row of stores... oh and the other place I suppose is Home Collection but they are pricey.
