I added these pillows for lift, is it the pillow I sleep with? most often not, is it uncomfortable? not at all. It is perfect for the under pillow to my favorite sleeping pillow and excellent to be the base pillow to prop up under the others for reading in bed. My son likes to use it as his primary pillow and it doesnt go flat if I make his bed everyday and fluff it up. However if he pulls his bed together in a couple days it has flattened quite a bit.
