Abstract
A chair height control mechanism has a gas cylinder with a valve control finger extending from an upper end overlain by a tilting actuator. A resilient pad is adhered to the upper end of the gas cylinder surrounding the valve control finger and maintains a spacing between the valve control finger and actuator when the actuator is not in use to avoid rattle.
