A deployable bleacher arrangement has deployed and un-deployed states and is provided with a plurality of seating level members, each arranged in sequentially elevated relation to one another. Each seating level member is disposed beneath an immediately superior seating level member in stacked relation when in the un-deployed state. In the deployed state, each seating level member is disposed beneath and forward of an immediately superior seating level member. A plurality of seats are disposed in side-by-side relation on a seating level member. Each of the seats has a bottom portion coupled to the associated seating level member for accommodating a user. The seat bottom has forward and rear portions and is arranged parallel to the associated seating level member. Additionally, a seat back is disposed in the vicinity of the rear portion of the seat bottom, and is pivotally displaceable with respect to the associated seating level member between a first position where the seat back is disposed orthogonal to the set bottom and a second position where the seat back is rearwardly declined to be parallel to the seat bottom. A linkage arrangement pivotally couples the seat back to the seating level member of the bleacher arrangement to secure the seat back in the first position. The linkage arrangement is releaseable so that the seat back can assume the second position. An unlocking arrangement urges the linkage arrangements associated with each seat into simultaneous release conditions.
