There were many variations on this design, such as the country brougham and depot brougham, and many broughams were later converted into hacks called growlers. One style of carriage had a folding child's seat inside, facing backward, but such a vehicle was called a coupé. Another was slightly longer, having a full-framed seat inside the front of the body, and was called a clarence. In the United States both the coupé and the clarence were also known as extension-front broughams.
