Water beds give a person optimum surface for sleep without any excess pressure and discomfort. The bigger part of the water bed adjoins with the whole body. That is why it adjusts to the contours of the body wonderfully. However these beds have some disadvantages. The thing is that people may have different weight distribution. That is why if a person has heavy thighs the water may shift to the area of shoulders. It causes squeezing of the shoulders. It may happen that some people like to sleep on one side. In this case the water bed may become the reason of spinal curvature. Some water beds are made of several chambers which are designed for two people.

Latex foam is also very popular. Latex is a natural material which represents milky sap of a rubber tree. The manufacture of latex mattresses does not pollute the environment. However the side effect is explained by the presence of crust which appears while manufacturing mattresses of natural latex.

The coils do not squeak because they are not fixed together. Many medics do not advice purchasing innerspring mattresses because the inner construction represents a place where dust is accumulated. In addition after a definite term of use the whole body is strained during sleeping on such mattresses. In the issue in the morning sometimes it is difficult to bend down and to turn one’s head.
