A support apparatus is described for use in the field of workstation design. The support apparatus is movably attachable to a seating device to selectively provide both dorsal and ventral support to a seated user. The support apparatus is movable, by a user in the seated position, between the position providing ventral support and the position providing dorsal support. Also described is a method of selectively supporting either the ventral or dorsal side of a user by one apparatus, the apparatus moveable by a user in the seated position.
