IF a plane's seat is comfortable without a parachute, a constant thickness rectangular container 24 long and 15"-16" wide like the National "Flat" or the Strong 303 should merely move one forward that thickness, leaving about the same comfort. It's about the size of a person's back, so it ought to fit anywhere a person's back fits. True?

Everyone's plane is buried in snow these days, so it's hard to do trial fits. :-(
