ABSTRACT:
A rocker-recliner chair adapted to rock or pivot between a forward stable position in which the occupant's head is higher than his feet and a rearward unstable position in which his feet are higher than his head, or any intermediate unstable position under the control of the occupant. The center of gravity of the chair and the occupant is forward of the pivot axis so that the chair returns by force of gravity to the forward position and drive means and controls therefor are provided so that rocking between said positions is controlled to relatively slow, continuous, smooth movement, and may be varied to suit the occupant.
