The article examines the applicability of Vischer’s model of comfort and fit for classifying the features of virtual workplaces used in mobile work. The user-centered model of comfort and fit was applied in the context of systematic literature review. The review showed that the model of environmental fit is useful for more detailed classification of virtual places and spaces. However, it seems that in virtual work the threshold of workplace usability rises from the physical level to the functional level due to accessibility demands. A mobile employee is forced to completely stop working if he/she is not able to connect. Compared to Vischer’s model the necessity level of the virtual workplace ascends to cover also the demands of functional fit.
