Blonde Girl Reveals Near The Modern Sofa Chairs

Chairs as sculptural and art forms
In 2001, Steve Mann exhibited a chair sculpture at San Francisco Art Institute. The chair had spikes that retracted when a credit card was inserted to download a seating license.
Later other museums and galleries were equipped with the Pay to Sit chair, with a global central seating license server located in Toronto. Patrons anywhere in the world could each receive one free seat license. The first seating session was free, with a database of persons who'd already used their free session.
