Query: Do NOT order these....severly underfilled!

These pillows are the worst I have ever seen. The filling is so lacking that, if you put your head on the pillow, it will fall right down to the bed. If you didn't know better, you'd think you were laying right on your sheet. I returned them as defective - I couldn't use them as pillows. It didn't matter what we did. We puffed them, fluffed them, and nothing. The pillow is too large for the puny stuffing inside. You just can't put any "pillow" under your head. Severely underfilled.
