side sleeper here with, female with broad shoulders. This is the fifth contour pillow I had had to alleviate neck pain and arm and hand numbness. Three others I loved, but they wore out quickly, one other was a super hard foam that was the right shape but gave me a headache because the foam was too hard (not memory foam). After reading reviews, I thought this pillow might be the best of all worlds of contour pillows. However, what I found is that the memory foam was too hard after a while of sleeping (or trying to sleep) on it, whiuc is crazy because initially I thought the foam so soft that I figured there was no way the pillow was going to be supportive. so, too hard for my preferences. Also, and this is probably the worst part for me, although the rounded ends are high enough for my broad shoulders, they are too rounded on the high ends to fit comfortably under my neck the way I like it. instead, my head actually lays in the rounded part, instead of sinking into the dip in the middle. This throws my body out of alignment, with my head sitting too high compared to the rest of my body, putting strain on my neck. Lastly, the dip in the middle is not wide enough from front to back of the pillow, so if I try to use the flatter side of the pillow, my head actually sits partly in the larger side, again angling my head and causing my neck to be strained. so, I am returning the pillow and going on the hunt for another one. in the plus side, there is nothing wrong with the workmanship, and I love the idea of the adjustability, but given the other things that don't work for me (the too-rounded large side, and the too narrow dip in the middle), the adjustability just didn't help me at all. Great concept, though, and I wish more pillows had this option.
