The bottom layer is 6 inches of support latex foam which provides basic support for the whole mattress, with a higher degree of resiliency than the comfort layer.
The 3rd upper layer is not as firm as the support core. The stiff bounce of support latex holds the body weight of the sleeper while the layer above it does the cushioning.
