I bought this two pack when it was on sale just so that my fiancée and I could test out how comfortable they really are, and we were not let down at all! We have been using them for a couple weeks now and we both agree that they are the most comfortable pillows we have ever used. They really help get your neck in a good position while you are sleeping, and that might be helpful for people who have any back problems. On each side of the pillow, there is a small 'hump' or ridge, if you will, and one is a little bigger than the other so you can choose which elevation level is best for you. You can see the 'hump' I am talking about in the product image. The only downside, if I have to mention one, is that out-of-the-box the pillow itself had an interesting odor to it. The manual inside actually explains this, and said to air it out for 24-48 hours before you use it. After doing so, it was fine. No big deal! All in all, this is a great product and I recommend that anyone who needs some good neck support at night give it a try!
