Hi FAUguy,
Hopefully they changed the quality/density of the polyfoam layers on top of the latex in the first 4 versions of their mattress. You can read more about the Pranasleep mattresses in post #3 here and in post #2 here and in post #3 here and in posts #1 and #2 here and a forum search on Prana (you can just click this) will also bring up more information and feedback about them as well. As you can see I would be very cautious here because of the thicker layers of lower quality/density materials they have tended to use in the top layers of their mattress which could be a weak link in the mattress.
You can see the specs of the Beautiful in post #2 here but the materials in the top 6" or so of a mattress (which is 14 ILD and 24 ILD in the Beautiful which are softer than the two soft layers in the Savvy Rest) will have a bigger effect on how a mattress feels for most people than the deeper layers in the mattress.
There is more about primary or “deep” support and secondary or “surface” support and their relationship to firmness and pressure relief and the “roles” of different layers in a mattress in post #2 here and in post #4 here that may also be helpful in clarifying the difference between “support” and “pressure relief” and “feel”.
