The science of making people happy or comfortable does not exist, in any way.
As a professional pilot, and as project pilot on two Sikorsky helos now in production, I can't say anyone (including all those above who complain about their helo seats) can make a seat that is comfortable for all pilots, world wide.
I have hear about people who would sue over seat comfort, and even heard of one nordic pilot who took disability because he was tortured for so many years in a horrible seat on the helo he had to fly. Poor baby.
I came up with a saying a few years ago, after giving up trying to find pilot consensus on anything:
If you want 23 opinions, ask 20 pilots. All opinions will be different and opposing, and some guys will have two.
I think we are bound to differ, and the only solution is to have seat choices (not adjustability) and let the pilot chose his own.
