Memory Foam Mattresses

Memory foam mattresses feature a visco-elastic memory foam core as the support system, rather than the traditional innerspring. Like latex foam, memory foam's ability to deliver both comfort and spinal support allow the foam to act as a support system in lieu of a traditional innerspring.
Memory foam responds to your body temperature by softening under warmth, allowing the foam to contour to your body when you lie down. However, this also creates a disadvantage because memory foam can sleep hotter than other foams. Serta has addressed this issue with our Cool Action Memory Foam™ featured in our KoolComfort and Cool3 by Serta mattress collecitons.
Memory foam can help to promote a more restful sleep because it provides significant pressure relief to help reduce tossing and turning that can cause an individual to wake up and shift positions during sleep. Plus, motion transfer is drastically reduced as it absorbs movement without affecting the other parts of the mattress.
Memory foam is typically denser than other foam mattresses. This makes it very supportive, but also heavier. It can be considered a good compromise between the comfort of a soft mattress and the support of a firm one for those who prefer a foam core mattress.
