Can you please help me find a cooling pillow that actually works?

I bought two my pillows for $150 and they still need to be flipped at night every 5 minutes. I was thinking about a purple pillow for $160, but I don’t want to be fooled again. What pillow or trick do you suggest? Like putting the pillow in the freezer for for 5 minutes or so? I prefer Bed Bath and Beyond or Amazon, but any place that is legitimate will work for me. There might be a Canada Post strike soon so I might have to order from UPS or Fed Ex.
