These pillows do not seperate out or lump up like other feather/down type pillows I've used. I like it for this reason and my husband doesn't for the same reason. I thought "Well if he won't use them, I will". He tried one night only... I don't usually like feather/down pillows but I love these. They are high quality and the covers that come with them are high end! I( have slept better than I have, no stiff neck no tossing and turning. I would recommed these pillows.
