Hello, Was working on a custom home built Foam/Latex Layered Mattress. Maybe the comfort layer would be 2" too soft. Sleepers weight on the mattress is 155lbs per person From bottom core up to top comfort layer: 2" Foamex HR 35(ILD) from Perfect Fit 3" Latex Topper 32(ILD) from Foam by Mail 2" Foamex Energia 24(ILD) from local source 2" Latex Topper 20(ILD) from Foam by Mail 3" Memory Foam 5.3 13(ILD) from Cloud9 Bedding Energia can be used as a mattress core component and is not like traditional memory foam. I think it's best described as a cross between latex and memory foam. Cloud9 Memory Foam 5.3 Topper is fairly firm. Cloud9 5.3 density 3" can be used on the floor, alone if you weight under 160. I'm not worried about it sinking alone but perhaps with 2" of latex combined, would be too soft? I have never felt latex except in the mattress store. Those were all full latex mattresses and fully covered. A variant I was considering....removing the 2" Latex 20(ILD) from the comfort layer and adding 2" 43(ILD) Foamex HR foam to firm up the base. But I would love to check out FBM 2" 20ILD on top of the memory foam. I could use some feedback from anyone about this mattress. People with flobeds or FBM latex. Any opinions would be really appreciated. Thanks for any information or opinions, Matt B. This message was modified Feb 18, 2009 by Phalse

I see what you mean about the comfort layer, so even 2" of 20 latex and 2" of foam would be pushing it. Don't want to mess up the comfort layer so I won't be ordering 2" + 3". Thanks for the info. Don't they use 6" of 32 ILD FBM latex as a Medium firmness mattress core, then add a comfort layer for a simple 8 inch bed? You could add a firmer base to this and another inch or two to the comfort layer for a 12" profile? Other sites list their 32-34 ILD latex as medium-firm and 36+ as firm latex. FBM latex is less firm than other latex or is this just a difference between the people writing the site information? Also I found a "sleep magic" brand bed
and also
The 10” thick Sleep Magic Venus Supreme features a top layer of very soft Quiltflex foam bonded to a layer of 8lb ultra-high density Venus pressure-relieving memory foam. The three layers of progressively firmer Energia foam combined with the bottom layer of very firm Reflex foam provide perfect support to the Quiltflex and Venus components. The energia foam in the last bed is "plush" 16 ild "firm" 24 "x-firm" 35 Energia could be used as a middle and firm support layer? This message was modified Feb 23, 2009 by Phalse

At least in my experience, ILD specs have been pretty much useless in trying to predict firmness. It depended on other factors: the type of foam, quality control by the company who produced it, whether the foam had attached batting, was glued to other pieces of foam etc. A softer foam, when glued to a firmer one, will take on a much firmer feel compared to the exact same foam when it's not glued to anything. So between all of that, we found it impossible to predict just from ILD numbers what might actually work. In the end nothing did work for us. Also, I think more has to do with people's sleeping positions and body proportions. Not to imply anything to anyone, but I think heavier people generally do better with foams than lighter people, and I know for sure that back and stomach sleepers do much better with foams than side sleepers. With latex in particular, it seemed any ILD caused us lower back pain. Not sure if it's just the type of support latex provides, or what the exact problem was.

Thanks for the help, you all have so many good points, I should rethink my idea. Which is why I posted here in the first place, this forum really saved me. Thanks again MB Real DIY men fix the car and mattress. This message was modified Feb 24, 2009 by Phalse

| I would agree with most of the respondents that you are going way too soft here.... Generally 2" or at the most 3" would be enough for most people in the comfort range. Any more than that and you are defeating your purpose. It's just for comfort. Get 6" or so of a good support layer and if you need more than that you can even get one of the foundation pieces that the mattress companies sell to give it more depth. |
