Memory foam is made from viscoelastic, a foam that changes its shape when heat or pressure is applied, and it spreads weight evenly across its surface. Once weight is lifted, the foam returns to its original shape. Polyurethane is typically used as a core that provides more substantial support. First developed by NASA for use in aircraft seats, Memory foam has evolved into a variety of uses including pillows, sports helmets, shoe insoles, and of course, mattresses.
This space age technology foam adjusts itself to conform to individual body types; providing exceptional support and pressure relief. This greatly assists in attaining proper sleep posture and spine alignment which is essential for alleviating back pain.
Another benefit includes relief from allergies.Memory foam is made of inorganic fibers derived from polyurethane foam. These fibers prevent the formation of allergy causing dust mites. Multiple independent research studies including consumerguide.org and sleeplikethedead.com, have yielded similar findings of around an 80% overall customer satisfaction for users of memory foam. This ranks considerably higher than traditional Innerspring spring beds.
Memory Foam by design, is a heat reactive foam that responds to the warmth of your body. For this reason, it tends to retain heat. Although the addition of cooling gels has been a great improvement, for those who "sleep warm", memory foam may still not sleep cool enough to create a comfortable sleep environment.
Memory foam remains for most consumers surveyed, a great choice for those seeking an alternative to traditional Innerspring mattresses. In general, these beds provide more than adequate support and greater pressure relief than their coil spring counterparts.
