Which side of the memory foam pillow do you sleep on?
I have a memory foam pillow, one side is raised more than the other, and the middle is indented. When I first got it in the mail, the my wife got it form the UPS guy and brough the pillow to me, I was in bed, and I slept on it on the narrow side, and slept OK. When I got up later i looked at the box, I noticed the person in the picture was sleeping on the larger side. Ever since then I’ve been trying to sleep on that side, I usually sleep on my side, and I’m just not enjoying it as much as I though it would. Which side should I be sleeping on or does it matter? It may just not be for me since i sleep either on my stomach or side. Are there any other good pillows out there?

The top.
the side that’s raised more than the other generally goes under your neck, but it is a matter of personal preference: do what is the most comfortable!!
First instincts would tell me to do what the picture person would do but the scientist in me would try and see what feels better/most comfortable rather than what’s proper
Either side is fine. It depends how much height you need or how much space you have between your neck and the bed.
Try both sides.
More raised is usually for Men.
Less raised is usually for Women.
