Unlike conventional mattresses, latex alternatives are breathable, keeping owners warmer during cold temperatures and cooler during the warmer season. Latex mattresses minimize pressure points by conforming to a person's body shape and afford better slumber by absorbing movements.
There are additional benefits to using natural latex mattresses instead of synthetic latex. Natural latex mattresses have no polyurethane foam, which is made with carcinogenic chemicals that are emitted into the air as the foam breaks down, plus other cancer-causing toxins such as formaldehyde or polybrominated diphenyl ethers (boric acid). Additionally polyurethane foam does not resist moisture, making for a suitable haven for dust mites, mold and mildew.
Natural latex is free of any manmade materials. On the other hand, synthetic or blended latex can be wholly or partially comprised of chemicals and petroleum with a similar cell structure. Synthetic latex lacks the proteins found in its natural counterpart. Scientists developed polymer-based latex during WWII. At that time, supplies of natural latex from the Far East were limited, necessitating a synthetic version which is an inferior substitute in the absence of quality raw material.
