ABSTRACT:
A mattress includes a mattress body and an elongated support. The body includes a fabric case and a pad contained therein, and is formed so as to have predetermined breadth and length. The support has a soft structure and is disposed at a predetermined lengthwise location of the body so as to extend in a direction of the breadth of the body. The inventive mattress is capable of serving as a health aid which is so arranged as to prevent the lower back region of the human body from sinking in a curved manner and also to press against the lumbar vertebra, thereby improving the blood circulation and assuring a comfortable sleep.
