I ordered my memory foam topper at last. I am getting the 2", and looking forward to finding out if it helps. A friend has one and let me lie on it to test it out. Felt nice, but of course one cannot tell from that - what matters is how it feels when you sleep on it and how you feel in the morning. I have a good mattress but it is several years old, so I think the topper might be the right thing. I found one that has great reviews, and doesn't cost very much at all. I will report in when I have slept on it.
