Hi alskling,
The better options and possibilities I’m aware of in the Madison area are listed in post #5 here.
One of these carries several component latex mattresses including Savvy Rest which are also 2, 3, or 4 layers of 3" latex with a cotton/wool quilted cover.
Some local manufacturers will also make layer adjustments to a mattress you purchase although you would need to bring the mattress to them to open it up and make the necessary changes.
I don’t recommend one or the other because it depends on the parts of each person’s personal value equation that are most important to them. There is also more about the pros and cons of a local vs an online purchase in this thread and the posts it links to.
I don’t make specific recommendations about “what” to purchase only about “how” to choose so that each of the forum members here can base their choice on the parts of their personal value equation that are most important to them (not to me). Both of these are members here which means that I believe that they both compete well with the best in the industry, neither one would be a mistake in terms of quality or value, and you would be making a final choice between “good and good” (see post #2 here).
