What is the function of a neck roll pillow? Do people use it in place of the regular pillow to sleep?
educate an average Joe here, I already asked this questin in home decorating and on answers.
lol, oops I mean I asked it in another category and got no answers.

The function of a neck roll pillow is not that of a replacement for a regular pillow; it’s to stop your head from falling back when sleeping while travelling.
My parents use them to support their necks when they sleep. I don’t really know if it helps but they say it makes them sleep better.
