A stairway forming system (10) is disclosed which includes a plurality of stacked, elongate stair riser form carriers (12-20) and an anchoring unit (24). The carriers (12-20) are longitudinally displaceable relative to one another. The anchoring unit (24) anchors at least the lowermost riser form carrier (12) in position relative to a substrate. A positioning assembly (44) is attached to at least one of the riser form carriers (12) and cooperates with the remaining riser form carriers (14-20) to displace the carriers. The carriers are displaced in unison relative to one other to adopt a staggered operative configuration approximating the angle of the stairway to be formed.
