Abstract
A portable bleacher seating structure includes an active descent and lift mechanism that includes a placement assembly having an arm and an arm wheel at a distal end thereof. A bracket connects the arm to a gas spring. The pressure within the gas spring opposes the arm as the bleacher is positioned in order to control the descent of the bleacher as it is tipped into position.
