Ergonomically designed seats are supposed to force you to sit in the "correct" posture to prevent back pain - However, since most people are slobs, we don't usually sit in the correct posture and so when we are forced to - with no choice - it feels unnatural and uncomfortable. And of course a seat that gives support in the correct places for someone who is 6' tall, will probably be uncomfortable for someone who is 5' tall.
I propose seat-type and legroom be decided by size. For example, Rows 1-5 be desingned for people up to 5'2" tall, 28" seat pitch and padding in the right places - going back to rows 30-40, 37" seat pich for those over 6' tall (me!!!!) The thoery being - the space between your knees and the seat in front should be the same for everyone. I know it will never happen - but its a nice idea. When I start my own airline, Air Disaster
, this will be one of my first policies
By the way - I'm currently looking for pilots with no prior flight experience, flight attendants with attitude problems and mechanics with previous lawnmower rapair experience - apply to my email address. Initial startup should be using MD-11s from Winnipeg(YWG) to New York(JFK) via Honolulu (HNL)
