As a woman who suffers with neck pain, I was very excited to review for Sleep20. Sleep20 is a pillow that has a built in chamber for you to fill with water and the idea is that it supports you better than a regular pillow, aligning your neck. I am also normally a stomach sleeper, but since I just had this surgery, I am forced to sleep on my back or side. This pillow really came in handy since I have had a hard time trying to get comfortable on my back.
Before I get too far into this review, I want to point out that this was a replacement pillow. The first pillow had a manufacturing issue and it caused the water to leak out. I have been assured this is not a regular problem and it has been resolved now. I was not at all angry, as I thought it was my user error as there is a specific way one needs to fill and cap off the water in the pillow. 
I must also mention that customer service with this company is FIVE STARS. When I told them about the leak, they immediately arranged for me to have the delivery driver come to my house and pick up the leaky pillow, no questions asked, and investigate the issue. It was found to be an extra piece of material inside the valve that was a mechanical error. I was promptly sent a replacement with no issues. This company really has exceptional customer service-something that is so rare these days I think!
The instructions that come with the pillow are very detailed and easy to understand. The pillow is very comfortable and soft. I made the mistake of not letting all the air out the first night I slept on it and it had some sloshing sounds kind of like a waterbed. After I re-read the instructions again and was very careful to make sure all the air was out, the second night was less noisy!
I did notice a difference in how my neck felt. I often suffer from morning headaches that I think are from me just not sleeping right on my pillows. I have noticed in the past couple weeks that they are less and less frequent. I belive this may be due to the Sleep20 pillow. The one complaint I have about it is when it is full of water, it is obviously very heavy.
You can purchase the Sleep20 water pillow on Amazon.
