Abstract

A cushion and a mattress are provided with a large number of options for an adjustable resilient characteristic, and it is possible to reduce the frequency of replacement of an old cushion being used with another new cushion. In the cushion, an upper cushion and a lower cushion each of which is formed with a filament three-dimensional bonded member are arranged to overlap each other in an up/down direction, the upper cushion and the lower cushion are interchangeable in position and are reversible in vertical orientation and at least three of the resilient characteristic of the upper surface of the upper cushion, the resilient characteristic of the lower surface of the upper cushion, the resilient characteristic of the upper surface of the lower cushion and the resilient characteristic of the lower surface of the lower cushion are different from each other.
