Purchased online from Tall Paul's Tall Mall, the 50-lb (23-kg), dark-blue, extra-long twin mattress is of the kind Columbia places in its dorms, similar to the one on which Sulkowicz alleges she was raped [REF].
Sulkowicz said the work would end when the classmate she accused was expelled from or otherwise left Columbia, and that she would take the mattress to her graduation ceremony if necessary [REF].
