I like the upper tier of the ikea down pillow. It has a double (or triple?) structure, with a different percentage of down / feathers in the chambers to make it soft but filled. As a side effect the filling doesn't move that much during the night :)

Edit: it's the Bergven that another commenter linked (thanks DoctorJuveTurkey!!): https://www.ikea.com/us/en/p/bergven-pillow-high-00460228/
