Hi buttercupbetty,
You’re right that there are hundreds of choices!
A suitable pillow is an essential part of good alignment for the head and neck and upper body because the gap between the head and the mattress and the curve of the cervical spine needs to be supported just like all other parts of the spine. Like mattresses … there are certain “needs” that depend on body type and sleeping positions (and on the firmness of the mattress you are sleeping on) but with pillows, personal preferences play a more important role because the face is much more sensitive to textures, temperature, smells, and other more subjective “feel” based properties of a pillow. There is more about choosing pillows in the pillow thread here and the other topics and sources of information that it links to that may be helpful as well.
Better sleep shops will often have samples of their pillows available for you to try (they should be in a pillowcase and not a plastic wrapping) so you can try different types of pillows and pillow materials in person and use your own personal experience rather than just “theory” to help you decide on the types of pillows and pillow stuffing you tend to prefer.
Hopefully some of the members that have tried the pillows you linked will see your post and share their comments about them or about other latex pillows you have tried but of course I would always keep in mind that their own needs and preferences or their experience on any particular pillow may be very different from your own.
I still like the Malouf zoned latex pillow I mentioned in post #3 in the pillow topic but my current favorite is still the Lanoodles pillow that I am currently sleeping on although of course I have only slept on a tiny percentage of all the pillows that are available in the market and my own preferences may be very different from anyone else’s.
