That is definitely vinyl. Though, they also have good reviews from 944 people who have put them of with good results. ANd they are half the price of the Lseat.
I was going to do the Lseat before I saw the Iggee covers. Now I might just do vinyl and see. The Lseats would be $340 for the perforated centers that I would like. $179 is half.
