Manufacturer: POWERMADD. Model Rev X. Installation is easy. Remove your seat (5 minutes), remove the staples holding on your old cover, insert the foam and recover with the new E.S.R. cover and re-install the seat.
Wasn't that difficult to do. Would be a little easier if you have someone help you at a couple spots. Found myself wishing I had a third hand at times but I managed. Looks great and the install was under an hour.
