8 Benefits of a Memory Foam Mattress

#1 Body hugging comfort

Memory foam is a durable, temperature-sensitive substance that molds to your body’s heat and weight. When you lay down on visco elastic, the foam conforms immediately to your body shape. Memory foam’s ability to contour to your body is what sets it apart as a superior material for mattresses.

Since memory foam conforms to your body and distributes your weight equally, it is comfortable no matter what position you sleep in. The spine is kept in a neutral position regardless of how you sleep on the mattress, whether on your back, side, or stomach.

#7 Customized support

Memory foam used to get a bad rap for making people too hot to sleep and for having the consistency of quicksand. The newer models allow for increased airflow, cooling down during the night and providing a personalized level of support. There are now low, medium, and high density memory foam mattresses available, each with its own level of comfort foam thickness.

#8 Sag free and no sinkage

Modern memory foam mattresses use adaptable high-grade ingredients to strike a balance between being too soft and too stiff. The open cell construction of the mattress ensures that it will retain its shape over time.
