Shelly did you end up picking something up?
Are having problems with the earlier mentioned daughter's mattress (and unfortunately also its mem foam replacement), so back at shop again this weekend. While there for the heck of it tried some Klufts (and loved their lower line, Aireloom, even more). That was before I saw their price tags (the store only carried the up to $20K mattresses ). http://youtu.be/cz0Eo2aDs_A
The Airelooms though are back to semi-Earth-bound McRoskey/Tempur-Pedic prices. They're a hybrid of ten/dozen layers of traditional and contemporary materials and were pretty fantastic. When GF & I are ready to replace our mattress I'm sure a base Aireloom will be in the running.
The salesman, a pretty nice guy whose been great dealing with our issues, also confessed his opinion that sex isn't quite the same on memory foam. Or as he put it looking at me "you have to do all the work and the older I get the less I want to do all the work."
