I’m undecided between 2 and 3
If your answer is more than “one”, it usually means you don’t have the right pillow for your sleeping position. I have broad shoulders and I was a side sleeper. I used two pillows for the longest time, otherwise I had to twist my shoulder in while sleeping, or tilt my head towards the bed, neither being really comfortable for long time periods. Then I bought a thick foam one on sale in some random store I was at, and it made a world of a difference.
I would use only one if I could find one I like that is thick enough. For a while I put two in one pillow case but the result was too oval in side profile.
Maybe some of those foam chunk pillows with adjustable loft. Basically the case has a zipper in it and you can move fill from one to another.
I bought a pair of these and some waterproof zip cases and ended up with 3 pillows I like instead of 2 because they both needed to lose about a third of their volume to be right for me.
One and it’s got to be pretty flat. Pillows in hotel rooms are so puffy, I can never sleep properly.

I have a pillow from Tempur (hard when cold, very soft when warm).
Upside: Pretty thick. About 8-12cmI can’t deal with more than one.
Wait, you guys have more than one pillow?
One, anything else is pure decadence (unless you have a neck issue or something).
According to science, anywhere from 1 to 0
A single pillowcube pillow.
To anyone wondering since it’s so often advertised, it does a good job as a pillow but it’s nothing revolutionary.
I use 4-5 because I have acid reflux 🤦♂️
You’re now the proud owner of a broken neck! How does it feel?
None, I sleep on my elbow.
Smart. Cost effective.
0-1 I like it flat.
