Abstract
An apparatus and method is provided for mounting a support column to a chair base having a cavity formed therein and tilt-control housing having a hub defining a core. The support column has a top portion and a bottom portion. The apparatus includes a support structure, a vertical shaft and a mass positioned within a vertical housing. In operation, the base is supported by the support structure. The bottom portion of the support column is placed in the cavity of the base and the hub of the tilt-control housing is placed on the top portion of the support column. An impact force is applied against the tilt control housing to simultaneously press fit the top portion of the support column within the hub and the bottom portion of the column within the cavity.
