Not everyone has the same posterior width! And it almost doesn’t depend on the weight!!!
What can one expect from a seat that is too narrow?
If we are sitting comfortably, it’s not too serious! It’s the ‘seated transition’ just after takeoff that will be more difficult…
Sitting too wide is very common and it’s not good at all!
The ‘seated transition’ is easy, but it’s the only advantage!
As with a ventral adjustment strap that is too open, the movements of the air mass are amplified by a seat that is too wide. One is swayed from left to right, which can lead one to think that the air mass is very turbulent and makes one lose confidence.
Behaviour in case of collapses is aggravated.
It is more difficult to load on one side or the other for ‘seat steering’. The path to travel is longer.
