I was wondering, in case of a 'water landing', what type of seat cusions are most effective as flotation devices? They are all probably at least somewhat effective (they couldn't say it if it wasn't true!) and since I hope to never actually test any of these devices, I was hoping one of you could shed some light on the situation.
I am not really up to date on the current cushion manufacturers, but I'm sure there must be a few. I would imagine that cloth and leather covered seats also exhibit differences, even if they are manufactured by the same company.
Also, what airlines use these 'best' cushions?
Are more recently designed and manufactured cushions more or less bouyant?
Do seat cushions lose bouyancy over time as they are compacted by passengers?
How much does the larger size of first-class seat cushions affect their floatability?
If anyone has first-hand experience with them - either in real life or possibly in the cushion testing lab, we would love to hear from you. If you would like to share your story on how a cushion saved you or a family member, please do!
As a follow-up, is the 'flotation quotient' taken into account during primary seat design, or is it merely an afterthought? To clarify: obviously they design the seat to float, but is it designed to float a certain amount from the beginning? If the final product doesn't live up to expectations, is the whole design scrapped?
