ABSTRACT:
A cushioning means, which contains a substrate sheet, bouncing cells made of elastic material convexly formed on one side of the substrate sheet, supporting cells made of elastic material convexly formed on the other side of the substrate sheet, each the supporting cell having a passage connected to the corresponding bouncing cell, and a liquid article such as water take part of the space between the surfaces of the bouncing cells and supporting cells. Since the space is not full of the liquid, an air chamber is formed in the bouncing cells. The cushioning means utilizes the low density and high compressible nature of air collaborating with the flowing nature of liquid for the comfortable and effective cushioning purposes.
