You can try putting them on www.Freecycle.com to give away in your area, or you can offer them on Craig's list.
You could recover them and use them as throw pillows. Most agencies Like Goodwill or Salvation Army would throw them out because of health reasons and restrictions.
The most success I have had with getting rid of items other could use that I do not want is posting on Freecycle.com in my area, as there is always someone willing to take the item off my hands. Joan
