I’m building DIY latex mattress for 2 side sleepers (~300 lbs total weight) with the following configuration:
6" Dunlop firm core (ILD 36)
3" Dunlop medium topper (ILD 28-33)
3" Dunlop soft topper (ILD 19-22)
I think the build has a core firm enough for back support and cushion soft enough for pressure relief. I also chose Dunlop for durability and longevity since the process produces a denser foam than Talalay.
Is the build good enough or it could be improved?
What if I proceed with the following build:
6" Dunlop firm core (ILD 36)
6" Dunlop soft topper (ILD 25)
2nd build is simpler with one layer for support and comfort layer but firmness is not gradual like in the 1st build.
Will 2nd build compromise support and/or comfort?
Which build is more durable?
Should I consider Talalay for the topper(s)?
Any suggestions are welcome.

As someone who has built their own mattress and still trying to perfect it, I’ll give this advice: go to a latex bed showroom first and eliminate what you definitely don’t like. You’re starting pretty standard, but be prepared for tweaking the layers. Starting with three layers of 3 inches each will allow for variations/switches if needed. Also are you assuming both sleepers are twins with exactly the same preferences? Because I recommend king size but purchasing 6 layers of twin xl size. You won’t feel the split the pieces won’t move or shift and that way you can play around with firmness combinations before decidingon exchanging or buying additional layers. Consider talalay for your top layer. And if you’re having unequal pressure relief between shoulders and hips consider zoned layer that’s customizable/interchangeable like from Flobeds.

I don’t have access to latex bed showroom but I had a chance to try Naturepedic EOS Trilux mattress (3 layers of 3" latex in soft-medium-firm).
Naturepedic doesn’t disclose ILD numbers but they use Dunlop latex.
Since I liked the feel of Dunlop mattress with its gradual firmness, I can try emulating it or improving it. The difference with the 1st build is that I’m using 6" firm core instead.
So you already own the foam core? I think the thicker six inch base may feel firmer or more supportive, perhaps an expert can weigh in. I too started with savvy rest in showroom and I thought I’d try soft/med/firm Dunlop too, as a 190 pound 6’2" side sleeper. But I found it both too soft and too saggy, and I used sleeponlatex Dunlop which some say is s little denser than other companies. I ended up switching out soft for a firm to make it med/firm/firm which was better support but not enough pressure relief. From there it got more complicated for me. So bottom like hour 6 inch firm under 3 inch medium under 3 inch soft may work, most people prefer a transition layer. I hope that helps.
