This is a good pillow for a stomach sleeper. In general, you should buy the soft one if you are a stomach sleeper, the medium one if you are a back sleeper, or the firm one if you are a side sleeper. I am a stomach sleeper, so I bought the soft one. At first I was worried that it was still too thick as it pretty well fills up my king size pillowcases, but it compresses to an appropriate thick for a stomach sleeper like me. I probably would like it even better if it was a little thinner, but with that being said, I have not had neck or back pain. It's also good to remember that the pillow is only one part of the equation. My wife and I replaced our old mattress that had developed divots where we sleep with a new very firm Simmons mattress (a very firm mattress has very little of the foam padding, which is the first part to wear out in my experience). We combined this very firm mattress with a 3" all-natural botanical latex topper. This has worked very well for us. I also like separating the topper from the mattress so that if one part wears out, we just replace that, rather than having to get a whole new mattress just because the foam layers are starting to wear out and develop divots. Our new topper did not fix our old mattress, it simply filled the contours of our old lumpy mattress. But on a new flat mattress, it is wonderful. I hope sharing my experience with the various factors that you need to take into account will help you to make an informed decision. There's nothing more frustrating than spending a lot of money on mattresses and pillows and still not sleeping any better -- hopefully my experience of what has worked for me and what hasn't will save you some cash and sleepless nights.
