Model 1972 is a round seat bar stool with a backrest and a decorative chrome pan. The chrome pan goes around the side of the seat. The back is attached to the seat on the underside with back-posts. Pictured is on a double ring frame with a swivel. We can also use a single ring frame that would allow this bar stool have a 24 inch or 30 inch seat height. With a 2 ring frame, it only comes in 30 inches.
