Y'all, I've tried every type of in-flight headrest thing - the turtle one, the space one, the tube around your neck, all the things...AND THIS WORKS. IT REALLY WORKS!!!! I was able to get a solid 4hrs of sleep on a 6hr flight and was so refreshed when I arrived. I cannot believe I hadn't known about these before. Even my husband, who never ever sleeps on planes, passed out.I recommend adding ear plugs to maximize comfort for sleeping. Seriously, buy these. If you regret it, it's probably a you problem — respectfully!! But also, find what you like and what works! And no, this is not sponsored...but like, if the company wants to send me another one for free I would happily take it and guard it forever!! ;)
