Please clarify anyone
Yes 
“Eco foam”, “plant based foam”, “green foam”, “soy based foam” and many other similar names are also all versions of polyfoam.
Memory foam names that include the same things like eco, plant based, green, soy based, and many other similar names are also just versions of memory foam.
There are no “natural memory foams” or “natural polyfoams” no matter what you may hear or what someone may want you to believe.
