I've decided that a kit is the way to go for us.  We've tested various memory foam and latex beds locally but the price of the latex is just too steep and after realizing how customizable the kits are, it seems like a no-lose proposition.  After the showroom tests, my partner really loves the feel of memory foam.  We've both used memory foam pillows for over a year and really like them. Has anyone tried the memory foam/latex combo from Flobeds?  Everyone here seems to stick to latex only.  Is there a reason for the avoidance of MF? 

Oh and for our stats:  I'm 5'6" and 190 lbs (side sleeper) with a back that needs fairly firm support  and he's 5'10" and 170 lbs and a stomach/side sleeper.

The flobeds adviser recommends firm over firm for him and firm over medium for me (which I worry won't be enough support), with a memory foam top.   I'm torn between this and going straight latex.  Any advice?
