Abstract
A chair height adjustment mechanism includes a lever positioned to overlay a valve opening member of a height adjusting cylinder. The lever may be depressed by a cam on a control arm when the control arm is rotated. The depressed lever then depresses the valve opening member. Depression of the lever through the rotation of the control arm may give finer control to the depression of the valve opening member than is conventional.
