ABSTRACT:
A chair includes a lower seat cushion member which is independently pivotable about a pivot on the chair frame and a rear back cushion member which is independently pivotable about a pivot on the chair frame. The rear and lower seat cushion members are not interconnected and are independently pivotable with respect to each other. The cushion members are preferably biased toward a neutral rest position with a weak biasing force so that the occupant of the chair can easily cause the cushions to pivot so as to assume the proper support position for the occupant.
