1. A method for producing a cushion with a casing made of an airtight casing material and a flexible, polydirectionally air-permeable filling body which is arranged in the casing and which is materially connected to the casing, wherein the method comprises at least the following steps:
a) coating a first mold cavity of a molding tool with a curable, flowable and/or sprayable plastic material to form a first casing shell,
b) coating a second mold cavity of the molding tool with the curable, flowable and/or sprayable plastic material to form a second casing shell,
c) inserting a pre-produced, flexible, polydirectionally air-permeable filling body into the first casing shell located in the first mold cavity before the curable, flowable and/or sprayable plastic material cures or fully reacts,
d) after steps a), b) and c), joining together the first and second casing shells located in the first mold cavity and in the second mold cavity before the curable, flowable and/or sprayable plastic material cures or fully reacts, such that the curable, flowable and/or sprayable plastic material of the first and second casing shells penetrates an entire surface on the filling body.
