Abstract
A height adjustment mechanism for a chair with a housing and an adjustment lever. The housing is fixed to the base of the chair and is slidably coupled to a post supporting the chair seat. The height of the seat above the base of the chair is dependent on a position of the post with respect to the housing. The adjustment lever is positioned within the housing and has two plates joined by a spring configured to bias the two plates in opposite directions. A free end of the adjustment lever is movable between a locked position and an active position. When in the locked position, the height of the seat is fixed. When in the active position, the height of the seat is adjustable.
