I'm not sure what you mean by a natural memory foam mattress. Memory foams are mainly made of polyurethane - and that is what this mattress is made of. There are a few new ones incorporating natural ingredients. The one "green" memory foam I've seen uses agriculturally derived ingredients that replaces some of the polyurethane.

Is this a natural memory foam mattress?
