ABSTRACT:
An adjustable lectern includes a base portion having a tubular upstanding base member and a tubular upstanding tower member that is mounted in a telescoping arrangement with respect to the base member. The base member and the tower member are each respectively formed as rigid tubes or channels by a single, unitary piece of material such as sheet metal. The lectern further includes a work platform that is positioned at an upper end of the tower portion. The work platform is both vertically and horizontally adjustable with respect to the base portion, so that both users who will be standing behind the lectern making a presentation and users who will be sitting behind the adjustable lectern in a wheelchair when making a presentation may be accommodated. Both the work platform and the base member include industry-standard rackmount structure for facilitating integration of electronic components.
