BFD headquarters is located in Michigan, on the shores of Lake Superior. Founded by Andy Gregg whom created the first Bike Chair, the company has since expanded the line to include everything from tables, bar stools, loveseats and more chairs.
In addition to bike parts, some designs use train and automobile windows for tabletops, and surplus automotive seat-belt webbing for seating upholstery.
While the prices aren't cheap, they are very reasonable for something that is both a piece of art and a functional piece of furniture. They also take donated bike parts and include them in their works!
