Document Type and Number:
Japanese Patent JP6990989
Kind Code:
B2
Abstract:
To solve problems for example, when enhancing flexibility for providing body pressure dispersion performance, required positions have to be selected for further enhancing flexibility and many grooves have to be provided on the selected positions, so that a number of selected processing positions and a number of processing steps are increased, and processing steps are complicated.SOLUTION: There is provided a mattress 10 comprising plural width direction grooves 12 which are opened to a surface of a base substrate 11 and extend in a width direction of the base substrate 11 on the surface of the base substrate 11 formed of a resin foam having a uniform thickness in a length direction and a width direction, in which the width direction grooves 12 comprise a groove bottom face part b in which a length direction groove width t of the base substrate 11 in an in-groove depth part is wider than a length direction groove width s of the base substrate 11 on a groove opening part a, the grove bottom face part being parallel to the surface of the base substrate 11.SELECTED DRAWING: Figure 1
