Abstract
A method of installing a spring into a chair and a chair with a preload member that prevents a user from removing an initial stress from the spring. The method includes positioning a spring guide in a first position and installing the spring into the chair in an unstressed state. The spring is then stressed by adjusting the spring guide away from the first position. When the spring has been stressed to at least the desired initial stress, the preload member is positioned to prevent the spring guide from being adjusted back to the first position.
