Emma Sulkowicz, artist and undergraduate at Columbia University, discusses her current endurance performance work, Mattress Performance (Carry That Weight), with Roberta Smith, co-chief art critic for the New York Times. They continue a conversation that began with an article in the Times and talk about the process of interweaving Sulkowicz's personal trauma with public work, the unique experience of carrying a mattress in public, and what it means for Sulkowicz's art that she has become an Internet-based media phenomenon.
