A chair back for a chair that includes a support frame portion having a defined shape and is adapted to attach to a chair base member. The chair back for a chair may also include a tensioning frame portion having a defined shape and a removable elastomeric support sleeve having an opening adapted to receive the defined shape of the support frame portion and the defined shape of the tensioning frame portion. The removable elastomeric support sleeve may be slid first over the support frame portion so as to conform the removable elastomeric support sleeve to the defined shape of the support frame portion. The removable elastomeric support sleeve may then be slid second over the tensioning frame portion thereby conforming the elastomeric support sleeve to the defined shape of the tensioning frame portion. The support frame portion may be adapted to receive and secure the tensioning frame portion, so that the force of connecting the tensioning portion to the support frame portion locks the defined shape of the support frame portion and the defined shape of the tensioning frame portion to one another along with the removable elastomeric support sleeve and therefore forms the chair back.
