I use this seat cover on my Phoenix 98623 Revolution Cycle Pro II Exercise Bike.  If you like cushioning, I would recommend that you continue to wear a pair of padded bike shorts in conjunction with this seat cover.  Otherwise, it does a fine job of making the stock bike seat more comfortable.  I also like that it is fully adjustable and you can tighten it with the pulley strings.  No problems with the seat cover slipping off or moving during my workouts.
