Hi carpetdenim,
Just in case you haven’t read it yet … post #1 here which has all the basic information, steps, and guidelines that can help you make the best possible choices.
They’re not a member of the site but they certainly make some good quality/value mattresses. They have recently gone through some changes since the owner died and his nephew Chris is now running the business. You can read more in post #5 - #7 here. A forum search on natural bed akron (you can just click this) will also bring up more information about them as well.
You can read more about the different types of latex in this article and in post #6 here. You can also read a little more about the difference in “feel” between Dunlop and Talalay in post #7 here but the best way to know which one you prefer (and it’s a preference not a “better / worse” choice) is to test both of them in person because “feel” is very subjective.
As you may know … SleepEz is one of the members here which means that I think very highly about them and they are among the best quality and value in the industry. Component layers mattresses with zip covers are certainly a very flexible design and allows you to customize the firmness and support of the mattress both before and after a purchase as well as replace individual layers instead of a whole mattress if that is ever necessary.
