These pillows are pretty good. I've had a hard time finding pillows that are full enough and firm enough for a side sleeper. I wish these were a bit more full and firm, but their pretty good. I have to admit I've been sleeping well on them. But as a side sleeper, I wish my head would not sink down quite as much in them. It would be better if my neck could be straight instead of tilting down a bit into the pillow, that's what I was hoping for. I haven't found the perfect pillow yet, and it's hard to do in a king size pillow. But these are as good as I've found yet.
