An ergonomic chair has a back support member and means for arranging and supporting legs of the user in an asymmetric configuration, with a first leg extending in front of a body of the user and a second leg aligned with or extending behind the body of the user. An angle between the first and second legs in a side view can be at least 30 degrees. The means for arranging and supporting legs can comprise one or more fixed structures that support the first leg in a first orientation, or one or more dynamic structures that can be positioned by the user to support the first leg in a first orientation. In some embodiments, with the legs of the user in the asymmetric configuration, a centerline of the user is offset from a centerline of the back support member with respect to a lateral direction.

An air distribution system is provided which includes a source of intake air leading into a conduit through which the air is forced by a fan or the like. Provision can be made for heating the air. The conduit is a rigid structure provided with a plurality of openings. In association with these openings, there are provided control devices of various types. One type of control device which is employed is used to change the direction of flow of the air upon the exiting of this air from the conduit. In another type of control device the diffusion of the air is controlled upon the exiting of the same from the conduit. Another type of device which is employed is an internal device designed to intercept at least part of the flow of air within the conduit and to divert the same through the associated opening. Some of these devices may be controlled by a signal generated at a remote signal source under the control of a sensor which is located in the area or enclosure in which air is to be distributed. The conduit may be supplied in sections and these sections may be telescopically engaged. The air supplied through the conduit may be heated or not depending upon the function to be performed.
