We just bought the 2012 Focus SE Sport to replace the 2011 Fiesta my wife had been using for work. She has a commute of 65 miles each way, and the Fiesta, though wonderful on MPG, had narrow, harder seats that were uncomfortable after awhile. The wider seats in the Focus have good padding and side support, and she is much more comfortable on her long ride every day. I agree with earlier posts about the side bolsters being less effective for a slim person (I am 6 feet tall with a 30" waistline). However, it is still a very comfortable seat for me. I think most average size body types will find the seats very comfortable. The fabric is also very nice, and breathes well. I don't seem to get that 'clammy butt' syndrome on a long ride.
