Hi LSUtgrboy,
Post #2 here has more information about the pros and cons of an all latex mattress vs a latex/polyfoam hybrid and also links to post #2 here which talks more about the Aloe Alexis which has two layers of latex (that has two layers of latex that can be customized or exchanged after a purchase) and would be more “in between” the two. This topic may also be helpful and for even more detail a forum search on “total latex mattress alexis” will also bring up all the posts in the forum that mention both of them.
There is also more about some of the ways that can help accommodate couples with different needs and preferences in the first part of post #2 here and there is also more about split comfort layers in post #2 here and for those that will benefit from a mattress that has a different firmness on each side they can certainly be a great option.
