It almost has to be intentional. Two sheets of plywood stuck together at 90° would be more comfortable than whatever it is they’re doing.
On the other hand, my wife is 5’4” and springs out of her seat after a four hour flight like she’s just had a spa day.
Only tangentially related, but the cheapest (by weight and per unit) type of hamburger patties at my local Costco this month are Impossible Burgers.
If you’re not familiar with these, they’re completely vegan, made from soy protein, but the texture and flavor is almost identical to beef. They cook like beef, taste like beef, and “bleed” like beef. And (for a few weeks, at least) they’re cheaper than beef.
That’s a new and exciting sandwich IMO.
