Hi! I have a king sized mattress (width approximately 10 inches) that I am looking to give away. All you need to do is pick it up. It is approximately 4 years old. 3 of the 4 years, it has been in an allergy protector cover so it looks and feels pretty new still. No spills ever on this bed. There are no dips or curves in the mattress to date. I see no reason why it cannot get a new lease on life somewhere else. It is a super firm mattress. I realized I need a softer mattress. If you are interested, or know of someone serious who wants it, contact me. Attached are pics of the mattress. Call me: 613-252-0965
