I recently bought this one and I like it the best so far. I went through about a half dozen pillows before settling on this one. https://smile.amazon.com/dp/B08J2B8G8Z?ref=ppx_pop_mob_ap_share
This is what I bought a few months ago and have been happy with it. I have C5-C7 fused so I also have a hard time with pillows. I went and tried about half a dozen from Amazon until I settled on this one.
