Hi rkate,
You can read a little more about the new Rejuvigel line here but as Novosbed mentioned it’s not that likely you will be able to find out the foam specs (which is odd because Anatomic Global is owned by FXI which manufactures the foam).
Guidelines always have “fuzzy edges” and when you are at one side or the other of the range then using “best judgement” would be the way to decide. Foam is not manufactured to exact tolerances and there will always be variances in any batch so choosing a mattress that may be just outside the guidelines in some way would be a matter of “best judgement” and would depend on specific circumstances, budget, and personal criteria based on your own personal value equation.
Foam quality has little to do with the suitability of a mattress and both are important parts of making a good choice. No matter what the quality or value of a mattress if it’s not suitable for your specific needs and preferences then it would not be suitable for you to sleep on and would have little value to you.
