You can see my thoughts about the organicroots descriptions in post #6 here.
In all fairness they do show that their mattresses have innersprings in the descriptions (including the description you posted) but I agree that there is no legitimate way to call polyfoam (soy based or otherwise) “organic” (see post #2 here). There is organic Dunlop latex available (see post #6 here) but given the other errors or misinformation in their listing it would be legitimate to question whether the latex they were using was organic and I would want to see some validation for this (Such as the organic certification for the materials they use).
You can see my thoughts about them (along with SantaBarbara Mattress and Spencer and Smith which is the name of the mattress they manufacture) in post #6 here.
I would be very cautious with the first and think much more highly of the second.
