TempurPedic is a name brand that produces mattresses made of viscoelastic foam. Viscoelastic foam is named such because it is a foam known for high viscosity and high elasticity. Viscoelastic foam was originally developed in the 1960s in conjunction with NASA. NASA commissioned a foam that would improve the safety and comfort of aircraft seats. The foam was developed because the polyurethane from which it is made reacts to body heat to soften the seat.
As the foam softens, it molds around the shape of the body to create a comfortable and relaxing seat. It quickly became used for mattresses. In the last 50 years, TempurPedic mattress technology has improved so that the mattress will form better to the body while reacting more quickly. Also, it does not store as much heat as a normal mattress would.
One of the biggest concerns for those shopping for a TempurPedic mattress in Temecula, CA is heat retention. Body heat makes the polyurethane foam conform to the body, but it also retains heat. New chemicals have been added to the polyurethane so that it wicks heat away from the body. One of the early complaints was that the beds would get very hot overnight. Nowadays, that is not the case.
You can find some of these newer mattresses at Action Appliance. They are available for many different types of sleepers as well.
People sleep in many different ways. There are some general rules of thumb about what is preferred, though. Side sleepers like a mattress that will support the back while also being soft enough to conform to the body. Back sleepers like a softer mattress that they can sink into. Stomach sleepers tend to like a firmer mattress that supports their lower back. There is a TempurPedic mattress that is right for just about every kind of sleeper.
