A method for forming a chair, comprising:

• inserting a first stiffener insert into each of two hollow tubular members at a first location;
• inserting a second stiffener insert into each of two hollow tubular members at a second location;
• after the inserting steps, bending each tubular member and first stiffener insert in an area of the first location and bending each tubular member and second stiffener insert in an area of the second location to form a front, a bottom and a back of each lateral side of a frame of the chair;
• after the bending step, connecting a seat to the front of the frame;
• and
• after the bending step, connecting a seat back to the back of the frame;
• wherein the back of the frame and the front of the frame are connected to each other only by the front bend, the bottom and the back bend.
