ABSTRACT:
An adjustable chair support comprises an upstanding spindle and a tubular standard telescopically received on the spindle for vertical movement relative thereto. Stop means are provided for maintaining the vertical position of the standard relative to the spindle. Actuating means contained within the standard are operable to release the stop means and thus release the standard from one such vertical position for movement to another vertical position relative to the spindle. The actuating means, though enclosed within the standard, are operable from without the standard at an upper portion thereof.
