Thanks for your earlier responses - your experience with latex seems to be rare in bedding. I noticed that you have said any disc related issue is not a good mix with latex but you also say that you don't know why its a problem. I've scoured the net for reasons why latex or foam would be a problem for back problems and really can't find much -- not even from my doctor. I would think that the wrong support is the wrong support any way you cut it right? Is the effect of individual coils, latex, and foam the problem and is there a resource to back up this claim. I would think proper spinal alignment is key so why is a regular spring any better than latex for disc issues? In fact, wouldn't it be the other way around if proper spinal alignment is the goal? You seem to have insight on this somewhat based on earlier responses and I like that you don't feel that latex is for everyone but the cons aren't clear. Thanks again.
