A chair rests on a raised platform, lined with black felt.  
The black square has a strip of brown rug that runs under the chair and extends past it.  
The chair is centered at the back of the platform.  Under the two hind legs, the platform has been cut away.  
A block of ice sits in its place.  As the ice melts, the chair leans back.  
Slowly, weight takes over, the chair slips out of formality.
