Query: Effective padding but not that comfortable in actual use

I bought this for my roadie. When I got the package, it felt like it would work out well, but the seat cover does not stay on very securely. It's constantly moving around.I think it would be more effective on a beach cruiser or something with a wide seat and where you won't be pedaling very hard. Then again for that kind of bike, you can just get a big fat seat, can't you?
