How anyone could give these any less than 5 stars is beyond me. These are THICK and FULL and plump and really wonderful. Yes, they have some feathers in them. They are not 100% down. I would not want 100% down Euro pillows. I need more body than that. The feathers give them body. I don't sleep on mine on a nightly basis because I bought them just for using to sit up and for decor. However I have fallen asleep on them and slept with them all night and they were very comfy. Maybe if you had really cheap thin shams the feathers MIGHT bother you, but I bought Ralph Lauren shams from Macy's and I don't feel the feathers at all. I almost did not get these because of the reviews from a couple people on here, but this is one of the best purchases I have made this year! I absolutely LOVE these pillows. They were completely plump about an hour after unpacking. Might not have even been that long. I highly recommend these pillows!
