Featherbed
Originating in Europe, a Feather Bed is a feather-filled bedding element providing support for the entire body. A featherbed is placed on top of a mattress, either under or over a fitted sheet, to create gentle support. It is made of feathers, encased within a feather-proof fabric shell, and possibly a down top. Construction will be either Baffle Box or Horizontal Baffle Channel or Vertical Baffle Channel.
