This invention relates to a mattress which provides a sound sleep to a sleeper.
Conventionally, it has been believed that bedding or mattress having a soft feeling assures a sound sleep. Furthermore, with the advent of foam rubber and spring mattresses, the type of bedding used today feels much softer.
However, these types, in general, are so soft that the spinal cord of a sleeper tends to bend downwardly during sleep. Therefore the weight of the sleeper cannot be uniformly supported by the bedding.
Due to the above manner of sleeping, a person often feels pain in his shoulder, waist or spinal cord.
To be more specific, since conventional bedding is made of extremely soft material, such as urethane foam rubber, the central portion (e.g. shoulder, waist or hip) of the sleeper's body sinks into the bedding.
Therefore, sufficient respiration to impart a sound sleep cannot be obtained while the blood is congested and the body temperature is high in those areas which come into direct contact with the mattress. Both of these prevent the sound sleep which also occurs on the part of the body (e.g. shoulder, hip or waist) that sinks into the bedding.
On the other hand, some people believe that a bedding made of hard material assures a sound sleep. However, in practice, this type of bedding is not suitable for any person except youngsters, since it causes the upward curving of the spine and the stretching of muscles.
Therefore, it is of vital importance that the ideal condition of a mattress be such that it is soft to the touch yet firm enough to uniformly distribute the sleeper's weight.
It is an object of the present invention to provide a mattress which can resolve the afore-mentioned defects of conventional beddings, including the spring mattresses.
It is another object of the present invention to provide a mattress which can enhance the circulation of the blood within the body as well as set the sleeper free from pains that occur in the shoulders or areas which come in direct contact with the upper surface of the bleeding.
It is still another object of the present invention to provide a mattress which is further equipped with a desired number of magnets which can effectively cure the deficiency syndrome of magnetic fields, such as the imbalance of autonomic nerve or the stiffness in the shoulders.
