Simmons Beautyrest with the indivicually wrapped coils — firm or extra firm, try it out in a store. I’ve been using them for some time and found them really great.
I tried sleep number mattress, since they had them in some hotels I stayed in, I did not like them at all.
I have a Temperpedic clone but don't care for how the memory foam absorbs body heat. I'm using a couple of mattress pads to insulate but still not satisfied.
Thanks, I think I’m going to have to *sleep around* a lot more before I purchase another bed. Nothing worse than buying a new bed and waking up with a backache.
