Hi Rink,
[quote]So what I’d like to know is which other manufacturers/vendors sell mattresses with Tatalay latex tops that can be reconfigured if necessary?

I think what you were looking for was this post #4 here and post #21 here. These posts link some of the better latex component suppliers and configurable latex mattress manufacturers of which I am aware.
Let us know what you end up deciding!
