ABSTRACT:
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.
