Though synthetic latex is more common and resilient, a small percentage of the population is highly allergic to it. For this reason, some manufacturers fabricate alternative products containing natural latex. Since quality sleep is crucial to one’s quality of life, the fact that some mattress manufacturers offer a natural latex option is extremely important. The natural latex is mildew- and mold-resistant, and because it is not created with any toxic substances, it doesn’t emit the fumes that will irritate and sicken those with chemical sensitivities.
