Hi kathering1,
Savvy Rest offers two types of latex. The first is 100% natural Dunlop that is certified organic which is basically the same material as the 100% natural Dunlop that SleepEZ offers without the organic certification. There is no organic Talalay so any of the layers that you tried at Savvy Rest that were certified organic would have been 100% natural Dunlop.
The second is 100% natural Talalay which would be the same material as SleepEZ offers.
If you know the type of latex in the mattress you tried at Savvy Rest then it would just be a matter of using the same type of latex and firmness level in a SleepEZ mattress.
There is more about the difference between Talalay and Dunlop in post #7 here.
If you know the layers that were in the mattress you tried at Savvy Rest then if you call and talk with SleepEZ they will tell you which of the options they have available are closest to the Savvy Rest layering that you were considering. If the Savvy Rest combination you were considering isn’t the normal suggestion they would make for your weight and sleeping positions then they may also suggest a layering combination that in their experience may be a better match for you as well.
