A seat cushion ( 1 ) with a seat surface wall area ( 3 ) and with a bottom surface wall area ( 5 ) has a bead-shaped transition wall area ( 5 ) which joins the seat surface wall area ( 3 ) to the bottom surface wall area ( 5 ). Thus, there is a fluid-tight cushion ( 1 ) which can be filled with air via a sealable fill opening, In two areas ( 11 ) which are adjacent with a distance from one another the distance of the transition wall area ( 7 ) from the middle ( 19 ) of the seat cushion ( 1 ) is increased, by which in an overhead view lens-shaped areas ( 11 ) are formed which project laterally over the essentially circular outline shape of the seat cushion ( 1 ) which is otherwise determined by the transition wall area ( 7 ). These projecting areas ( 11 ) are supports for the thighs ( 17 ) of an individual ( 17 ) sitting on the seat cushion ( 1 ). Even for a small diameter of the generally circular surface-shaped seat cushion ( 1 ) this yields good sitting comfort, since the thighs ( 13 ) are supported at least in the area adjoining the buttocks ( 15 ) by the projecting supports ( 11 ), as would be otherwise only for a seat cushion with an altogether larger diameter.
