The biasing mechanism has a first portion attached to the first member adjacent the first end of the first member. The biasing mechanism also has a second portion attached to the first member adjacent to the second end of the first member. Preferably, a second member is also provided that is moveably attached to the first member. The second member may be configured such that movement of the second member actuates height adjustment of a chair.
