Hi there, currently have a talalay latex mattress and its incredible.
My current mattress has 3 layers of 3 inches each.
1x 22ild
1x 30ild
1x 39ild

Im looking at a new mattress for my move and giving this one to my folks.
The one I'm looking at is 8inches total and 4 layers of 2 inches each. (talalux)
1x 17ild
1x 24ild
1x 30ild
1x 40ild

Curious how much softer people think the second mattress would be and also if there is a big comfort difference between 3 layers and 4 layers.

Let me know!

Hi hayden14,

There are really too many variables, unknowns, and individual subjective perceptions involved to accurately predict how a mattress will feel for a specific person except in very general terms.

The fact that a mattress has 4 layers isn't nearly as significant as the specifics of the layers. For example there would be little difference between a mattress that uses two 3" layers of the same material in the same firmness level as a single 6" layer. If one of the two 3" layers are different from the original 6" layer in the type or firmness of the material then there could be a significant difference.

Having said all that ... I would guess that the mattress with the 2" layers would likely feel noticeably softer for most people since the foams on top (which are the most significant part of the "feel" of a mattress) are softer. I don't know how to quantify "how much softer" since this would be very subjective and would vary from person to person based on individual perceptions, body type, and sleeping positions.

Hey phoenix thanks for the info.

My plan is to actually now go 3in 22 ild x 3in 31ild x 2in 39 ild.

My support layer will only be 2 inches, is that a problem? Will it be a big difference between a 3in support layer?

My other option is to do High denisty foam of 4in as support layer which will sav eme a little $ but i dont know the true comfort difference between the two.

I either have to go 8 in or 10 in mattress as I am building my own and those are the only two sizes the cheapest latex mattress covers i can find come in. If you know of any other zip covers under $100 in different sizes then I might be able to check it out.

But overall I think the 8in would feel very similar to my 9 in at home unless that extra inch of support layer makes a big difference, and then worse case if not big enough i could go the 4 in support of high density foam?

Let me know what you think

Hi hayden,

My support layer will only be 2 inches, is that a problem?


It would probably be more accurate to call the middle and bottom layers your "support layers" but that's just semantics and there is no clear line between which layer is a comfort layer and which is a support layer. All the layers of a mattress interact together and will affect all the other layers to various degrees but if the mattress as a whole is a good match for you in terms of PPP then the thickness of any individual layer isn't an issue. You can see for example this latex mattress that uses a 2" layer of firm Dunlop on the bottom, a 4" layer in the middle, and a 2" layer on the top and there is no inherent issue with a 2" bottom layer.

Will it be a big difference between a 3in support layer?


Every change in a mattress will have "some" effect on the feel and performance of the mattress but the difference in adding an inch to the bottom layer would be relatively small. Different people are more sensitive than others to smaller differences so some people may feel it and some may not.

My other option is to do High denisty foam of 4in as support layer which will sav eme a little $ but i dont know the true comfort difference between the two.


This is another one of those changes that some people may notice and some may not if the top 6" of the mattress and the cover was the same. It would also depend on any difference in firmness between the latex and the polyfoam but the only way to know the difference it would make for you would be your own personal experience and comparisons.

But overall I think the 8in would feel very similar to my 9 in at home unless that extra inch of support layer makes a big difference, and then worse case if not big enough i could go the 4 in support of high density foam?


The top 6" of your mattress is very similar to the one you are building and the upper layers are the biggest part of what you "feel" so if the type and blend of latex is the same in both, all the ILD's are accurate, and the cover is very similar, then it would probably feel quite similar to most people.
