The standard seat cushion for the size 3 Wombat Living, supplied with its cover. The surface is flat, which gives a user with reasonable pelvic control room to shift their own weight and reposition during the day.
A flat base also leaves the seat clear for hip supports, a pommel or a pelvic belt, so the chair can be built up around the user without fighting the shape of the cushion.
It is thick foam under a breathable cover, and the cover is removable for cleaning.
