I've only used this in the car so far but I really like it. This keeps my head in place so that I don't end up with a sore neck. A regular neck pillow would push against my cheeks and make neck stiff without the backrest while this is thinly padded so I can still feel the ergonomics of the seat. The eye mask is also padded so it doesn't sit onto my nose making it feel like it's hard to breathe. Some of these details are minor but it helps so much -even how the eye mask is velcroed onto the sides so every time I try to get up it doesn't feel like I'm in a hostage situation.One improvement that I think would be great is if the eye mask was attached with magnets so that it doesn't make a noise whenever I remove it.
