I bought this seat cover to replace the one I had on my exercise bike, which has a wide seat, and it works great. It's a little longer than the seat is, but that really posed no problem. Like all gel seat covers the gel moves around to conform to the shape of your butt and your movement. I replaced the old one, a different brand, because it had became lumpy and misshapen after a long period of time. So to prevent that with this new one I remove the cover about once a month or so, depending on use, then realign it back on the seat, to prevent the lumping. So far so good.
