Cardinal Timothy Dolan proudly displayed the armchair Wednesday at the Garden.
It has a light brown finish with a darker mahogany trim and a white cushioned seat, back and arms.
The pope will wear green vestments and preach in English and Spanish on Sept. 25. About 200 deacons and 150 volunteers will assist him.
The readings will be said in English and Spanish. Other prayers will be in Gaelic, Polish, German and other languages.
The chair was constructed by a group of day laborers in a suburban New York garage.
Inmates at a Philadelphia prison are also constructing a chair for the pope's visit there.
