Summarize this article:

After determining what type of pillow you think might be right for you, look around online. Read reviews for different pillows before going shopping, especially if you are thinking of buying a special pillow, such as an anti-snoring or cooling pillow, which can be expensive, and may not do what it claims to do. The best pillow for you may not be the most expensive one. Try out different pillows in different price ranges. Many stores that sell pillows also sell mattresses. If you can, take the pillow and lie down with it for a few minutes to try it out. This will give you a more realistic idea of whether the pillow is right for you or not. If you are unable to lie down with a pillow, try standing next to a wall in your favorite sleeping position. Place the pillow against the wall. If the pillow you are testing works with your body, your neck should be aligned with your spine. It may be difficult to tell on your own if your neck is not aligned, so bring a friend along to help you. Some stores, such as Ikea, offer the opportunity to return your pillow if you are not happy with it. Before purchasing a pillow, ask about the return policy.

Summary:
Read reviews online before going shopping. Understand that price isn’t everything. Lie down with the pillow. Stand close to a wall. Ask about trial periods and money back guarantees.
