Yeah I'm sort of wondering about the need for air ride seats if you already have air suspension. I've never had the pleasure of planting my arse in an air ride seat but do you really need it? Does it really help that much?
I was told by someone that some buses have troubles with some seats including air ride. Is there a width consideration in some coaches? Maybe arm rests, lack of set back distance from pedals to rear wall or rise behind seat etc?
Lastly, I'm sure it's a dumb question but why couldn't someone just mount their already owned or favorite seat into one of these air seat suspensions or similar? Maybe a height problem or ??http://www.buytruckstuff.com/product.asp?selcategory=16&p_gpID=208
