Hi msanchez,
I don’t keep track of all the mattresses that are sold in each area by their material content or construction details (and manufacturers change what they make on a regular basis as well), especially to the level of specificity you are asking about, so I really don’t know.
I would suggest talking to the smaller manufacturers on the Atlanta list though to see if they make anything like what you are looking for.
Besides the manufacturers on the Atlanta list … there are also a couple of others in Georgia that may be worth calling and talking to.

Some wholesale manufacturers that are sold through retailers may also make similar mattresses such as the Restonic here or the Therapedic here but I don’t know which retailers in any particular area may carry these of others that are similar. Even some of the iComfort line uses a mix of memory foam and latex in the comfort layers such as here and here[/url].

Some of the online members of the site that sell memory foam mattresses also have mattresses with a mix of memory foam and latex in their comfort layers (or could make them).
