Lifespan of support layer- latex or HD foam

[phoenix]

Hi Everhart,

I’m convinced latex is the way to go for us in terms of comfort layers. My question is regarding the support layer. In my research, there is at least a $500- $1000 increase for total latex vs a hybrid. I’ve read that the support layers do not bear the brunt of wear on the mattress.

Yes … the weak link of most mattresses is the comfort layers and a mattress will generally soften or break down from the top down. There is more about the many factors that are involved in relative durability and the useful life of a mattress in post #4 here and the posts it links to. there is also more about the difference between a latex/polyfoam hybrid and an all latex mattress (or a mattress that uses more latex in the upper layers) in post #2 here and the post it links to.

bonded foam/latex (not sure what this is?

You can read more about it in post #6 here.

Finally, I wonder about the off gassing potential of support foam- not sure if it’s relevant when it’s deep in the mattress. However If that’s an issue, the scale is tipped more in favor of all latex.

If the polyfoam is made in North America and/or is CertiPur certified* I don’t think that most people would have any issues with offgassing (although if a material does produce harmful VOC’s then it wouldn’t matter where it was in the mattress). Some people however that have a more restrictive answer to the question of “how safe is safe enough for me?” may prefer to avoid all polyfoam or synthetic materials completely but this would be a small minority or those who may be more sensitive (such as having MCS or multiple chemical sensitivities).
