Purchased another Stearns mattress and within 6 months it sank 2", I had to file a claim and this is the second one I purchased. The other was discontinued so I was at first worried about a firm pillow top that my store had but one nights sleep was good. I have severe back pain and needing a hip replacement in 2 months. So far feels great. Wasn't too firm. Comfortable to sleep in. Hoping this one will last! Can't say yet if it helps with pain because I'm in a lot of pain but I know the last one was great at first.
