I am rather picky about pillows. So far I have found 2 that work well.
The first is Sleep Better by Carpenter and endorsed by National Sleep Foundation. It looks like a big yellow square. Any attempt to find a buy now link is missing. But here is a picture. https://www.amazon.com/Better-Perfect-Luxury-Sleeper-Standard/dp/B0050EEMGE I have found this at BonTon type stores. They tend to last about 5 years. I now use a BedWorks pillow from Denver Mattress. I was able to try out a number of pillows on the bed type that I sleep on. The original price was around $90, but it was on clearance for $40.
