Didn't take anytime to get used to it at all. It is harder than the stock for sure, but when you order it, you tell them how much you weigh and they adjust the foam from there. super lightweight as well. It is pricey too, but I started to do one of those Rev to ZX seat conversions, and by the time you buy two seats (you don't want to cut up yours in case it doesn't work) and the reupholstering, that's pricey too. I would get in touch with Blutooth from Team Kesslers/Lake Effect Supply. He placed the order for mine with BOSS. Great guy to deal with. If you are going to do it though, order it well before the beginning of the season. BOSS isn't usually fast getting them out. (Not a knock) they just put out an awesome quality seat so it takes time.
http://www.boss-noss.com/seatbuilder/index.asp Go here and build your seat first, then when you order it you can send this to L.E.S. and he can get you a quote from there. I'd pull the trigger and no regrets. Just my opinion.
