Acquiring an electric height adjustable desk is the easiest way to convert your workstation so you can alternate sitting and standing during the course of the day.  But a new desk is not always possible or the best solution.  The tools in this section will retrofit an existing work surface for sit to stand use.   In some cases, you may need  to add a monitor arm that offers enough height adjustment range to work well for sit stand use. Choose from the popular Ergotron Workfit-A, Workfit-S or the TRU Sit Stand Bundle.
