We purchased 12” adjustable memory foam mattresses 3 years ago from Relax in Comfort. As mentioned, cost-wise it's akin to buying a small car so I wanted to build in some flexibility. Considering that we may downsize in the future, we elected to pay a bit more and get two twins rather than a split king to give more options in room arrangement. Also the mattresses are heavy! I don't go around moving mine but at least with a twin I don't need a crane to shift it around. Twins also allow each of us to choose his preferred position.

We like to read in bed so the ability to be more upright is much more comfortable than holding a book overhead (plus if one nods off, the book doesn't fall onto your nose).

Comfort-wise, we're pleased. Usually we sleep “flat” but occasionally I slightly raise my feet and head for a comfy cradle. Our remotes allow us each to program 4 custom positions.

The beds also have a massage (vibrating) function. After the newness wore off, we find we don't use this much.

The first time we left on a trip, I unplugged the beds along with the PC, TV, etc. Won't do that again! Reprogramming the two bed remotes so that a bed only responded to the signal from “its” remote was a bit complicated. We did it, and rewrote the directions in easy “steps” but we still haven't unplugged again.

Way back when we were in our 30's, 40's, and 50's (and not particularly hippie) we had a waterbed. Nothing fancy, just a king-size bladder filled with heated water. Maybe I just slept better then, but it was the most comfy sleep of all!
