Hi jsjs54,
I saw the specs on their site but they don’t mention the thickness of the layers.
There is more about the most important parts of the value of a mattress purchase in post #13 here and there is more to the "value of a mattress than just the amount or cost of the materials but knowing the thickness of the latex or the amount of the wool or cotton can also help you to make more meaningful comparisons with other mattresses.
