An incliner chair has a back and seat unit mounted on a base by way of slanted tracks and wheels at the rear and swing links at the front so that the unit can move by gravity from a rear upright position to a front recline position. Positioning linkage means for holding the unit in the upright and recline positions is provided and this may be activated by a short stroke handle concealed between the side of the unit and the base. A leg rest assembly is connected to the unit to move with it and provide a means to return the unit from the recling position to the upright position.
