Memory foam pillows - yuk. I've tried them and I always feel like the pillow is trying to smother me 😵💫 I guess I'm a down pillow person through and through.
Very detailed, helpful reviews. However, I have been sleeping on a My Pillow for a while. I find it too lumpy feeling, and also experience pressure on my ear that becomes uncomfortable and sometimes painful as the night wears on (I'm a side sleeper). I haven't found any reviews that address this ear pressure issue.
I saw another review comparing the Coop to the Saybrook Adjustable Pillow and the reviewer preferred the latter. I would have liked to have seen your evaluation of the Saybrook.
