Mattress Foams and Breathable Covers. Many people prefer to use a memory foam, such as Memorex, that conforms to your body shape and almost eliminates the effect of your sleeping position on your partner. When used in conjunction with a hard foam layer, it can provide you with a firm mattress that offers a high degree of comfort to your body’s pressure points such as hips and shoulders.
Traditional mattresses tend to spring back when force is applied. This ultimately causes you to toss and turn throughout the night, particularly if you are a side sleeper. The mattress pressing up against you reduces blood circulation in those areas, and your body at some point tells you to turn so you can get full circulation. Because memory foam sinks down instead of rebounding against your body, then blood can circulate freely as it normally would. The result is less tossing and turning throughout the night, more sleep, and feeling invigorated the following morning.
