I moved from my home state to another state several hundred miles away for work, thinking it would be more temporary. So now I’ve been sleeping on an not very comfortable spring mattress since then. My previous mattress, I ignorantly bought primarily off of reviews on Amazon & bought it from Amazon as well. I actually liked that medium firmness memory foam mattress. It actually was an upgrade over the previous all latex mattress that was a solid 8” max. slab of medium soft firmness.
Anyways, recently I’ve been researching products I buy way more thoroughly than I used to. Here’s what I came up with.
*DIY = do it yourself *HR = high resilience *HD = high density
I have found a DIY build & through a member company listed here & discussed the build via phone with them. So now I have a planned mattress configuration build that I’m fairly confident will work for my weight/ height/ BMI/ sleep style/ personal preferences.
It’s as follows: All layers use >95% all natural dunlop latex foam. 5” base/foundation (core) layer firm (38 ILD). 3” support layer (28 ILD). 2” top comfort layer (19 ILD). I intend to hold off on buying the top layer until I give the mattress a good test run, as I might not even need it. This mattress is intended to be slept on one side only.
I could purchase this today, as I believe I found good quality dunlop latex for likely the most reasonable price out there (it’s with the same company I discussed this build with). However, I found a good quality high density foam at well under half the price for that 5” base/foundation (core) layer & a few other HR/HD foams as well that I haven’t counted out as possible replacements. The comfort/support layers would still remain the dunlop latex.
What I’m not positive on, is how the ILD #’s & firmness given for dunlop latex equates to the IFD #’s & firmness given in HR/HD polyurethane foams. I see different companies rate their >95% all natural latex typically between 38-44 ILD = firm. Then I see the HR/HD foams typically rated firm = 45-50 IFD.
I believe from what I’ve researched, that the ILD & IFD #’s are quit similar when it pertains to how they relate to the foams I mentioned in this post. If so, that means I should get an IFD # approximately equivalent to the 38 ILD. That way I get the proper support, regardless of the firmness feel. I value support over comfort, which probably won’t even be felt, being buried beneath 3-5” of support/comfort layer. So I believe I should target a 38 IFD HR/HD foam to replicate the 38 ILD support of the dunlop latex, even if the firmness feel isn’t exactly replicated. Three of the companies in the running have 38, 40, & 41 IFD #’s. The other 2, including the front runner have either 35 or 45 as options. So 35???
I just would like to know if I’m thinking along the right lines with all this. If not, please set me straight & maybe there are better options that I’m overlooking as well. I’ve only been researching mattresses for one week.
