depends indeed.. ever heard of Q fever? but it isn't really the feathers per se just being around farm animals and is contracted from inhalation of particles .. of course they cause severe allergies to others.. but you know you can just wash them and remove the allergens..
I sleep on a feather bed and my comforter is of feathers too, so how about you invest in a feather bed, you might not want to collect feathers after that?
very cushy.. get read on them before purchase.. don't buy duck feather, just down (Hungarian) and cured ..
and Allah swt knows best
