I sleep good enough in coach that I'm sufficiently rested the next day, even if I have a seatmate overnight.
I think a large part of it has to do with a person's attitude. Many convince themselves in advance there is no way sleeping in coach could work.
My last train trip I slept 2 consecutive nights in coach, had a Roomette for 1 night, and then slept 2 more consecutive nights in coach.
I had a neck pillow and a travel blanket with me and both definitely helped.
I've slept in way less comfortable circumstances from time to time. Like sitting to sleep on a narrow rock ledge 1800 feet up a cliff in Yosemite Valley during a snowstorm.
For warmth we each had a bivouac bag, a down jacket w/hood, and wool mittens.
You just tie an anchored rope around your waist so you don't fall to your death if somehow you fall off the ledge
I've never had trouble with people on their cell phones
No doubt, I sleep better in a sleeper.
