The Chair Bombing  is a simple and low cost urban tactic, replicated in various cities such as, New York, Philadelphia, Dallas, and Santiago, Chile.


The first registered Chair Bombing was performed by a group called DoTank:Brooklyn, in New York City.

In Latin America, Chair Bombing has been implemented by Ciudad Emergente in Barrio Italia, Santiago, Chile, in alliance with the class “Tactical Urbanism” at the Universidad Diego Portales.

Chair Bombing has been mentioned in the New York Times as a Tactical Urbanism method. The first Chair Bombing event was held in Brooklyn and directed by the urbanists Aurash Khawarzad, Ted Ullrich, Tom Peyton, Vishwadeep Deo and Ken Farmer.

The Chair Bombing’s objective

The Chair Bombing exercise seeks to validate an assumption about the need for public space designed for pedestrians and for street furniture in the streets of certain neighborhoods. The experimental activity developed to test the hypothesis involves the temporary placement of furniture in different parts of a neighborhood.


Any city where one seeks to test the need for street furniture and quality public space meant for pedestrians.
