A podium 1 comprising a plurality of panels 30, 40, 50 configured to form a frame when assembled, a ladder unit 10 pivotably retained on the frame and a deck unit 20 pivotably retained on the frame. Further disclosed is a securing member 60 pivotably attached to one of the panels being releasably secured to another of the panels to create the frame of the podium when assembled, and the deck unit being releasably securable to the panels when assembled. There may be a gate section 71, 72 having a biasing towards a closed state, biased by a gravity hinge (44, fig 20). To collapse the podium, the panels are pivoted to be substantially parallel. Further disclosed is a gravity hinge arrangement comprising two sleeves (111, 102, fig 21), one having a slanted cam surface 103 and the other a cam follower 113 having a locked and a deployed state, the latter allowing rotation by gravity.
