At first glance, this pillow looks like it might feel "lumpy". When you put your head on it, however, all the little foam bits "align" and create a wonderful, breathable support and a great night's sleep. I took a little foam out of the one for my head and left everything in the one that I wrap my arms around. It's perfect, but I'm keeping those extra foam pieces for down the road! No kidding here: after years of subtle neck pain that I thought I'd just have to live with, after the second night on these pillows, it's been gone ever since!
