A friend of mine has them in his sami and they are allright but for $30 more apeice, you could step up to PRP's. Mine were $169 ea. and they are a true suspension seat and you can get any color, pattern etc you want.
I went with the high back bucket
bought them thru Kartek but there are now a few vendors on Pirate that may give you a better deal. middle of the page, they are listed as Kartek seats but they are PRP's
