ABSTRACT:
This invention relates to a chair having a tilting back that tilts rearwardly when the user leans rearwardly and that follows and supports the user's back as he leans forwardly. A lever, swingably mounted to the chair, responds to the specific weight of the user to carry the chair's back forwardly to comfortably support the back of the user without any required adjustment.
