Description

  The present invention improves the appearance by forming the mat into three parts by making the mat into a rectangular shape, and by providing a mat body that receives the waist part in the vicinity, the amount of depression of the waist part at bedtime. The present invention relates to a folding bed that can adjust body weight, distribute body weight, and maintain a natural sleeping posture for comfort of sleeping.

  The human body is composed of four blocks: head, chest, waist and legs. The weight ratio of the four blocks is usually 10% for the head, 35% for the chest, 45% for the waist between the abdomen and the knee, and 15% for the leg under the knee. It is said that the “preferred state” is that the body center line that connects the zenith and foot arch and supports the body in a straight line passing through the center of the thickness of the abdomen and straightens the spine. This condition also applies to a series of integrated mats from the head to the leg, even when the mat hardness and rebound resilience are made constant by adjusting the mat hardness, for example, at the waist (especially the heel) where the thickness and weight ratio are large. It is generally considered that the condition of the “preferred state” is easily achieved.

  On the other hand, for example, as disclosed in, for example, the prior art document 1 and illustrated in FIG. 17, in recent years, the bed frame a has been folded into an inverted V shape, for example, with the center portion up and can be folded for convenient storage.
