this is such a GREAT topic, thanks for starting this conversation. I see that Nancy has shared a lot of great existing resources that will hopefully be of help in your search. My personal experience with pillows is that the cervical pillows support my head and neck best. What I didn't know until recently is that there are different "profiles" of cervical pillows. So, there's a low profile pillow if you don't want too big of a contrast, and vice a versa. So if that's something that's of interest, but be aware that they are options even within the cervical pillows. I also like the cooling pillows. I have a "chill" pillow now and that simply helps to keep my head cooler. Keep us posted on your search and what you ultimately decide upon!
