I am a side sleeper, as I have lower back discomfort at times and cannot sleep comfortably on my back. Although I prefer a firmer pillow, memory foam pillows just didn’t work for me — until I tried Spherehead Pillow. It has been very helpful. After using Spherehead Pillow every night for the past four months, I’m happy to say that I now sleep comfortably and soundly on my back as well as my side. Spherehead Pillow has really been a game changer for me.
