The doona differs fron the quilt, eider-down and duvet in that it has a removable, washable cover thus eliminating the need for cover sheet and blankets.
The word is Swedish implying that it is filled with down, although the great technical advance was that it was actually filled with non-allergenic polypropeline padding. The name comes from an
advertising campaign in the 1960's in
Australia by the
furniture company, Ikea.
