It's more like sitting for 3 hours with your legs crammed into somebody else's back

Some* people have bad backs or joint problems, you acorn

Some people are a bit taller. Think of it more like three hours perching on a toddlers stool with sharp plastic corners digging into your knees. Think of it as three hours hunched over from the “head rest” digging into your back. Think of it as three hours with your arms pulled tight into your lap so you’re not elbowing your neighbor. Think of it as three hours sitting twisted so everyone’s shoulders fit together like jigsaws since seats aren’t wide enough for shoulder to shoulder
