Embrace Sleep Collar has expanded to Embrace Travel Products.
Here are a couple nice media reviews of the Embrace Sleep Collar Travel Pillow:
You Never Knew You Needed
"Ends the irritating head bobs that come with sleeping while sitting up. It gently supports your travel-weary head and neck from the sides and front as opposed to some blow-up pillows that shove your head forward".

"When you doze off while on the move, does your head slowly droop forward or to the side, before you are uncomfortably jolted awake? The Embrace Sleep Collar keeps heads and necks in proper alignment, supporting the neck all the way around". -Group Travel World Magazine 9/13

When you are sitting up and trying to relax, gravity is the enemy. Without full support gravity will take over and as your neck muscles try to relax, your head will drop forward or you will cock it to one side. You have lost your posture.
Now you are out of alignment and the weight of your head is placing stress on your neck. In addition to being uncomfortable and unable to relax, you will likely be sore and get very little rest. Remember, the average adult human head weighs 15-20 pounds. Pick up a 20 pound weight the next time you're in a gym and think about that tugging on your spine as the plane bumps and jars.
