I just got back from a road trip through England and I can tell you: I slept on terribly uncomfortable pillows! They were either too flat or too thick or just not as comfortable as my pillow at home. I missed it shamefully and therefore decided to just take it with me on vacation next time.
Which pillow makes me so happy, you want to know? It is this one from the traditional company Albis Bettwaren: The 'Fibrasoft' is an easy-care, synthetic pillow that I would especially like to put on the heart or under the head of vegans. The content consists of micro-polyester flakes that adapt to your head naturally.
And here's the kicker: if you want the pillow firmer, you can easily open the zipper and refill it. You can optionally buy the bag with additional content.
