A dynamic workspace module is provided for open plan spaces, and the like, and includes a compact footprint, comprising a freestanding framework supporting a three-sided partition to form an interior workspace and a portal opening for user ingress and egress. A door partition shaped to selectively close the portal opening is movably mounted on the framework. The door partition preferably has an arcuate plan shape, and is positioned adjacent one side of the portal opening, such that shifting the door partition from the fully open position to the fully closed position both increases the amount of the interior space in the workspace module, and alters the plan shape thereof for improved freedom of user movement, while alleviating any sense of user claustrophobia.

An adjustor for chairs with tilting backs and the like, comprises a threaded spindle connected with the chair back, and a gear wheel threadedly mounted on the spindle. The gear wheel is retained in a housing attached to a relatively stationary portion of the chair, such that when the chair back is tilted, the spindle rotates the gear wheel in the housing. A pawl is shifted into and out of engagement with the gear wheel to selectively lock the chair back in a wide variety of different angular positions.
