Abstract
A cushion structure that does not cause pain to a user when seated and that promotes steady breathing. Three dimensional knit fabrics are formed as a laminate of plural stacked layers, and a minimal-layer structure section, which does not possess at least even a single intermediate layer between the topmost layer and the bottommost layer, is provided on the approximate center section in the width direction in a prescribed width and in a prescribed length from front to back. The approximate center section in the width direction of the cushion structure is the region upon which the area around the sacrum is positioned when the user is seated.
