We bought a new mattress and took a chance on a Memory Foam mattress from Sam's Club. We love it. It is very comfortable, not hot as some have complained about Memory Foam, and the best part? I don't feel it when DH moves all around at night. "He is a very *active* sleeper!) We did not buy top of the line (the thicker the foam the more expensive) But we got the 13" Queen size for a very affordable $400 delivered in a long box. Laid it on the box spring, opened the plastic and watched it unfold. It did not smell. And we slept like babies starting the very first night.
