Mattresses are the hardest household item to give away. Very few charities take used ones for health reasons, so it pays to call first. The places listed here say they take mattresses or bedding.

A mattress with stains, tears or bed bugs belongs in your city's bulk trash, not a donation pile.
New, still-wrapped mattresses are welcome at many shelters.
