Abstract: A foldable workstation is rendered mobile by a mobile support structure. The mobile support structure comprises a pair of castor support rails, each castor support rail attached to a vertical support. A horizontal member joins the two castor support rails. Castors attached to each support rail provide mobility. To facilitate attachment of the foldable workstation to the mobile support structure, a vertical support cover plate is attached to each rear leg of the foldable workstation. Each cover plate includes a channel for receiving one of the vertical supports. In this manner, the foldable workstation is mobile and can therefore be positioned in any location desired. Castor locks permit the foldable workstation to be securely positioned.
