A chair includes a base having a vertically extendable gas spring with an upwardly disposed release button movable horizontally/laterally between a vertically oriented locked position where the gas spring is lock and non-extendable, and a laterally shifted actuated position where the gas spring is released and extendable. A seat is mounted on the gas spring and includes an actuator constructed to selectively move the release button between the locked position and the actuated position with a sideways movement. The actuator includes a link slidably mounted to a control housing under the seat for horizontal movement, and a lever that is pivoted to a side of the control housing for operating the link. The link includes an aperture with angled side surfaces configured to facilitate downward assembly of the link onto the release button, but so that the side surfaces will actuate the release button when the link is moved laterally by the lever. |
