Latex vs. Memory Foam
Memory Foam is the product of NASA research into ways to protect astronauts from harmful G-Forces. All Memory Foam, regardless of the manufacturer, is derived from this research and utilizes polyurethane based foam.
The market for Memory Foam mattresses has exploded in recent years as technological advances have spurred the development of new products. Latex and memory foam are the two types of foam mattresses that are widely heralded for revolutionizing the bedding industry.
Latex and memory foam mattresses do not have springs or other metallic arrangements and both take the shape of pressure applied to the surface and rebound to the original shape once pressure is relieved. This body contouring relieves pressure points and associated discomfort. These types of mattresses are widely claimed to be more durable than traditional mattresses. And beyond that, they are hypoallergenic and dust-resistant making them a health breakthrough for allergy sufferers.
Latex mattresses are made of synthetic or naturally-derived latex and memory foam is a visco-elastic substance derived from polyurethane. Because of the memory foam’s properties it is the softer and more pliable of the two. Visco-elastic mattresses are also temperature sensitive and react to body temperature to form a mold-like structure. When the temperature subsides the mattress gets firmer.
Latex mattresses are firmer than memory foam mattresses and are made of a naturally derived material, usually rubber. However toss and turn movements are felt more across the bed than in memory foam mattresses.
Because body-contouring qualities are more prevalent in memory foam than latex, users reporter greater relief from aches and pains especially in the back. In general, memory foam mattresses are also less expensive and have a longer life-span. Latex beds have not been around as long as memory foam products and therefore there is less long-term data to adequately predict life-span.
