A locking mechanism (11) suitable for use with office type chairs comprises an operating lever (13) movable between a first position in which locking takes place and a second position in which unlocking takes place, spring means for biasing the lever (13) into said first or locking position and catch means (23, 27, 29) for holding the lever (13) in said second or unlocked position on movement of the lever (13) into said second position. The catch means (23, 27, 29) is disengageable by movement of the lever (13) past said second or unlocking position allowing the lever (13) to return to said first or locking position under the action of the spring means.
