After we were in the meantime switched to synthetic (here I'd like to expressly warn against we purchase pillows: "Billerbeck 5453420002 fiber pillow S 22, 80/80 cm, white, clumped within a year and is not to be used), we are now back with feather / down pillows and these here are great! They can be in the form of hugging (has the fiber pillows never worked, not even when it was harder and harder) and you sleep great on them. Finally a pillow that does what it is intended, namely guaranteeing a comfortable sleep!
