Description of the Related Art Although it has been conventionally practiced to use a closed cell or an open cell as a component of a flooring material, even those flooring materials which are actually on the market have a G value (maximum value). There is no acceleration of 100 or less. In order to make the G value 100 or less, it is necessary to make the foam layer thick. However, this causes various problems such as bad walking feeling, large recesses due to static load, and unstable furniture.
