It has been generally accepted that apart from yellowing visible light has little effect on foam properties. 48 49 This is especially the case if the yellowing happens on the outer portions of a large foam as the deterioration of properties in the outer portion has little effect on the overall bulk properties of the foam itself.

Choosing between Polyurethane Foam Memory Foam and Latex Foam SleepOnLatex.com.
Latex foam offers several significant advantages over memory foam and polyurethane foam. Latex foam is a foam produced by vulcanizing liquid latex into a solid foam. The vulcanization process cross links latex particles with sulfur through the application of heat and accelerators such as zinc oxide. Latex foam can be produced with natural latex which is harvested from rubber trees or synthetic latex which is produced from petrochemicals. All of the latex foam we sell contains only natural latex and never contains any synthetic latex. Latex foam provides exact pinpointed support and reacts instantly to your every move.
