Abstract
Seating mechanisms enable the user to vary the seating angle of a chair or stool by enabling at least the portion of the chair that supports the thighs to be tilted forwardly to controllably increase the seating angle while maintaining the spine and pelvic region in vertical alignment. The extent of forward tilt is controlled by pressure applied by the user's thighs that also serves to counterbalance the weight of the user's torso.
