Give them a few days
Size: Queen - 18" X 28", Number of Items: 4
When I first saw these pillows I thought "no way". Even after 3 days they still were pretty sad looking. I read the reviews and people said to give them time and I am glad I did. These pillows are so nice and comfortable. I am glad I purchased them and glad I gave them time.
