Could be good for sleeping on your side, depends on your mattress also! So try before you buy.
I am 6 ft tall, have moderately broad shoulders, and it just happens that both sides don't support my neck properly. One side too low for side sleeping, the other side is actually too high, even for me.
Sleeping on my back actually hurts my neck cause it's too high in the middle part of either side. And I like to sleep on both side and back. So a versatile pillow with the right shape to accommodate both sleeping positions is important for me.
With my current mattress, this pillow hasn't been good. With another mattress, side sleeping was my only sleeping position using the low side of the pillow. I thought I was only a side sleeper till I moved out and changed mattress.
And normal pillow cases crease and swivel a lot as its not designed for this kind of pillow. I have just discovered Tempur do their own pillowcases.
