Mattress Forum

Long story shortened....back hurt with the mattress, I complained, they gave me store credit, I started learning about this stuff.
Ended up here and about 3 mos later bought a Foam by Mail mattress and topper.  Total bill was about $1000 for the 8" of latex, the mattress pad and the foundation pieces to go under the mattress.  My setup is in the featured section - as I took a lot of pictures to show how it came and all.

Its here... http://www.whatsthebest-mattress.com/forum/my-foambymail-8-latex-mattress-actual-setup-pictures/4091-A-1.html

This setup was a bit of a compromise with my wife and I as I am a stomach sleeper and she a back/side sleeper. I would have preferred a touch firmer, she a touch softer.
I have 6" regular base and 2" soft topper. all latex. with the costco cuddle bed pad.
Would like to try and firm my side up a bit....
My question for the experts here:
Do I split the topper, get a twin xl firm 2" - would that firm it up any at all?
Or do I really need to split the 6" base... 1/2 regular   1/2 firm? and how do you cut the stuff?

Anyone have any experience with this? Can I do this?
Good to see the site still here.

Thanks,
