BetterNeck Neck Pillow 13" x 10" x 3"

There are several options to consider but the most important is what is your sleep style? If you sleep on your back then a medium density pillow is the way to go. If you sleep on your side then a firm density is the way to go. Finally, if you sleep on your stomach then a soft density is the right choice.Of course pillows are subjective so regardless of filling down, feather, polyester, buckwheat or whatever else try getting a pillow that offers you the right amount of neck support.The memory foam pillows are rigid and are good for some sleepers the downside is they can be expensive and can not be hugged or molded to fit a shape you like. They are also not machine washable. I also like PrimaLoft which is a luxury alternative. It is sold in soft medium or firm filling onoptis and ranges from $20 to $60 with most in the $30 to $40 range.The goal is to have a pillow which will allow your neck to stay aligned more with your back based on your sleeping position.
