get those pillows that have a bunch of memory foam bits! i love our bamboo pillows since you can take out however much foam you want, and if you take too much out you can just add more fluff back in
I tried so many pillows and then I discovered the Coop pillow. It's shredded memory foam and comes with a bag of extra filling so you can remove or add to your liking
Yes, 2 different pillows of different firmness. Firm thick pillow for bottom. Softer medium size pillow for top.
Or two Goldilocks medium pillows depending on your preference.
2 small pillows or two large pillows doesn't work. Hotel pillows are usually excellent. So check the firmness when at a hotel to see what you like best. Often there are former or softer in the cupboard.
