Density is the most commonly talked about attribute of a memory foam mattress. In general, higher quality beds are made from higher density foam and shoppers look to density as a way of assessing quality in a mattress. High density memory foam beds are more expensive because they have more foam per bed, but they offer better support and more durability.
According to the definition from Wikipedia, Memory foam is made from polyurethane with additional chemicals that add to its viscosity level, thereby increasing its density. It has been gaining popularity in recent years seeing the declining manufacturing costs.
Memory foam is designed to support the entire body from head to toe. It will give you the exact amount of support you need by recognizing your body weight and temperature. It will actually contour to your sleeping position and cradle your body for a great night of sleep.
But do not get scared away. Generally speaking, if you suffer back or neck pains, then memory foam mattress could be the solution. The memory foam mattress is soft and it forms to your body night after night. and your spine will be in the right alignment.
Foam is made up of thousands of tiny cells. The cells are formed by a polyurethane wall and filled with space (air). Higher density foams have thicker cell walls and less space inside. Lower density foam has thinner walls, greater space. If foam were made too dense, its cell walls would be too thick / stiff. It would be hard to the touch and would not conform to the body properly. It costs more to make dense foam, and at some point it can be made too dense. So there is a balance that needs to be struck between performance, cost, and durability. The marketplace today has gathered around a 5 lb memory foam mattress as the optimal choice for bedding. While more expensive than lower density foams, it provides better, long term contouring support.
