  The three-layer structure mattress that demonstrates such excellent effects is based on the supine posture as the basic sleeping posture, and can be used even if it can maintain a comfortable sleeping posture in the supine posture. When the person is in a lateral position, the back is not straight and a feeling of pressure is generated in the shoulders and buttocks, and it is not sufficient to maintain a comfortable sleeping position.

  For those who fall asleep, often have a scoliosis, have back pain, or have a bent back, they often feel a pressure on their shoulders or buttocks because they often have a scoliosis. It was difficult to obtain a good sleep state.

  Therefore, in the present invention, although it is possible to cope with the supine posture, which is the basic posture of the sleeping posture, to some extent, it is not possible to cope with the lateral posture, and it is necessary to feel a feeling of pressure on the shoulder portion or the buttocks when recumbent Provided a three-layer mattress that supports the supine heel that solves the shortcomings of the three-layer structure mattress and provides suitable sleep and sleep without feeling pressure on the shoulders and buttocks, as well as in the supine posture There is to do.

  In order to achieve the above-mentioned object, the three-layer structure mattress corresponding to the supine heel of the present invention is made of a synthetic resin foam material in which the upper layer of the vertically long mattress comprising the upper layer, the middle layer and the lower layer has a restoring force against compression. As a material, a large number of protrusions are projected on the upper surface, and the middle layer is made of a synthetic resin foam having a certain degree of hardness with respect to a load. In a three-layer structure mattress in which a hollow portion is formed at a location corresponding to the above, and the lower layer is formed of an elastic synthetic resin foam material having a restoring force, the wavy convex portion and the hollow portion of the middle layer are in the lateral direction. In addition, a plurality of longitudinal grooves perpendicular to the wavy convex portion and the hollow portion are arranged in parallel on the lower surface and / or the upper surface of the middle layer portion corresponding to the collar portion from the shoulder portion of the user. Shoulder of time and / or And removing the tightness of the shoulder and / or hip by a sunken and softness of the portions corresponding to the buttocks than other parts to increase.

It is characterized by.

  Further, the groove formed in the middle layer is characterized in that a portion corresponding to the shoulder portion and the heel portion of the mattress user in the longitudinal direction of the mattress is deepened and the other portions are shallowed.

  Further, the mattress composed of three layers of an upper layer, a middle layer, and a lower layer is divided into a plurality of portions in the vertical direction, and is connected using a cover for storing the divided mattress.

  Further, the mattress composed of the upper layer, the middle layer, and the lower layer is covered with a cover whose lower surface can be opened and closed so that the mattress can be replaced.

  According to the present invention, the upper layer of the vertically long mattress composed of the upper layer, the middle layer and the lower layer is made of a synthetic resin foam material having a restoring force against compression, and a large number of protrusions are provided on the upper surface thereof. The intermediate layer is made of a synthetic resin foam having a certain degree of hardness with respect to the load, and is formed with wavy irregularities on the upper surface thereof and with hollow portions formed at locations corresponding to the wavy convex portions on the upper surface, In the three-layer structure mattress in which the lower layer is made of an elastic synthetic resin foam material having a restoring force, the wavy convex portion and the hollow portion of the middle layer are formed in the lateral direction, and from the shoulder portion of the user to the heel portion. Corresponding to the shoulder portion and / or the heel portion when the user is in a lateral position by arranging a plurality of longitudinal groove portions orthogonal to the wavy convex portion and the hollow portion on the lower surface and / or the upper surface of the corresponding middle layer portion. Softness and sinking of the part The lost tightness by spine larger than the other portion is straight, thereby to obtain a suitable sleep onset and sleep state.

  In addition, the depth of the groove corresponding to the sagittal diameter from the user's shoulder to the upper arm corresponding to the central portion of the mattress in the horizontal direction in the plurality of grooves formed in the middle layer is made deeper than the depth of the outer groove. When the user is in a lateral position, the shoulders and buttocks are positioned deeply in the deep groove and the back muscles can be straightened, and when the user is in the supine position, both shoulders and both sides of the buttocks are deep grooves. It is possible to maintain a suitable sleeping posture without excessively sinking the shoulder and the buttocks.

  The groove formed in the middle layer sinks the shoulder and buttocks with a gentle slope by deepening the part corresponding to the shoulder and buttocks of the mattress user in the vertical direction of the mattress and shallowing the other parts. This makes it possible to maintain a more suitable sleeping posture.

  Further, the mattress composed of the upper layer, the middle layer, and the lower layer is divided into a plurality of portions in the vertical direction, and can be stored in a compact manner by folding the mattress by connecting with a cover for storing the divided mattress. .

  In addition, the mattress consisting of the upper layer, middle layer, and lower layer is covered with a cover that allows the lower surface to be opened and closed so that it can be replaced. In order to cope with this, the corresponding parts of the lower body part (for example, the head / shoulder part, the waist part, the buttocks part, the thigh part, and the lower leg part) can be exchanged to adjust to suitable hardness and cushioning properties. As a result, the user can select and use a three-layer mattress with ideal hardness and cushioning according to his / her physique and the presence or absence of back pain, and can obtain a smooth sleep and sleep state. Needless to say, it solves the shortcomings of the traditional three-layer mattress, which had excellent lumbar pain treatment and spine correction effects and had to have a uniform structure regardless of physique and back pain. It is possible to enjoy the synergistic effect peculiar to the three-layer structure even more effectively.
