Early on I had to sleep on my back with padding wrapped round my elbows, as they were sensitive to pressure from mattress...
Now I mostly side sleep using a generic tempurpedic contour pillow, the smallest size worked best for me at first but now the medium is fine.

There are so many shapes now, basically if large framed a larger size/thickness small frame smaller size.
I would ask about return policy for costly ones , just in case it doesn't fit well for you.


I tried a cheap micro bead type, but the smell and the noise they made bothered me too much LOL..

As Coop mentions find something that fits and doesn't place your head/neck out of best position..
