Which side of the memory foam pillow Do you sleep?

I have a memory foam pillow, one side has improved more than the other and the environment is indented. When I arrived in the mail, my wife is the type of UPS and pillow Brough For me I was in my bed and slept on the near side and slept OK. When I get up late, see the box I realized that the person who sleeps in the picture on the longest side. Since then, I tried sleeping on that side, I usually sleep beside me and I do not like as much as I thought it would. Which way should I sleep or is it important? This might just be not for me since I was sleeping on his stomach or side. Are there any other good pillows out there?
