It needs to be re-covered with ticking, this is specifically made to be used with down/feathers, one note not all ticking is the same this is one item I really would want to see/feel in person. Some companies have fabric that is printed to look like ticking but is not the real deal.
Addionally big difference between down and feathers. Feathers have a bigger quill on the feather that is what comes through the fabric. Some feather items have such a large amount of quill in them that the best ticking will not keep it from coming through.
