You have to break it in first. It doesn't just conform to your body after one night. I had a memory foam mattress for nearly ten years and it wasn't great. Then we got a pillow top mattress which was just the worst thing ever. We've had a new mattress for a few months now and it's been really good.
What are we talking about? Oh, yeah. Uncle Ted should take that crappy mattress back. Hopefully it's still under warranty or whatever and he can get his money back.
