I got a MyPillow a while back from a friend (republican, feels like he tricked me lol). Didn't make the connection until a week ago. They ain't even comfy. You can get one of these for the same price and is leagues better.
I use this pillow and it stays very cool. It can be a little weird to use at first since you have to shape it how you want but once you get it right it stays that way and it’s very comfortable. I like having different types of pillows so I got the thin and the normal ones. Thin are better if you like to sleep on your back or front, normal are pretty thick but good for side sleeping and propping yourself up to watch a movie or something.

Mine is this one - https://www.amazon.com/Pillows-Sleeping-Hypoallergenic-Pillow-Sleeper/dp/B00V909F1K. A friend of mine stayed the night and liked it so much she bought one for herself. I’m a side/stomach sleeper if that helps.
I have this one (shredded memory foam, good for side sleepers) and I really like it! https://www.amazon.com/dp/B00V909F1K?tag=thewire06-20&linkCode=xm2&ascsubtag=AwEAAAAAAAAAAT0l
