Sorry, a pillow is a hygiene product. I really hope that something like this cannot be "tested" and then returned. For such fun, I recommend going to a specialist shop where you can try it out.

The Swiss family business "elsa" even offers the possibility to test a neck pillow at home.

"Well, you can make sure which pillow suits you best with our free test at home. Now at your pharmacy, drugstore or health specialist."

I had done that at the time, so I switched to this type of pillow about 15 years ago. I currently have pillows from Tempur and from billerbeck for different purposes.

just don't take it out of the plastic or try it in a shop first.
