I liked it better out of the bag

I have had this mattress (spring version) for two or three months - plenty of time to break it in. To be honest, I liked it much better right out of the bag. It is not a rolled mattress - comes full sized in a well-packaged bag. It was firm but supportive....until it broke in. I had no back or neck pain at all during the break-in period and now I wake up every morning with some pain and stiffness. I'm bummed. Did a lot of research before buying. The memory foam mattress may be a better option, but I don't know if I'm going to go there. At least the return policy is great.
