The existing inflatable beds generally have uniform softness and material on the surface of the mattress, thereby forming an integral sleeping support surface. However, because each part of the human body exerts different pressure on the mattress during sleep, the supporting force of each part of the existing inflatable bed corresponding to different parts of the human body is different, in terms of sleep comfort and durability There is room for improvement.

technical problem

In order to solve the above problems, the object of the present invention is to provide an elastically adjustable inflatable bed, which can balance the different pressures exerted by different parts of the human body on the bed surface, thereby improving the sleeping comfort of the human body and the durability of the mattress.
